Computer Mouse

Friday, June 6th, 2008

The computer mouse has definitely made a long journey since its inception in 1964. This input device is used for pointing and function selection. It is necessary for convenient and efficient work and play. These days it is not only used for pointing the cursor but can control almost any aspect of the PCs operation.

Computer mice are of four types - Mechanical, Optical, Laser and Trackball. Mechanical mice are the traditional ball models that are bulky and require cleaning from time to time for efficient performance. Dirt and small particles can get caught up in between the rollers and has to be cleaned using cotton and a solution. The optical mouse, however, do not function in this way and have no rollers or balls. They use an LED and sensor (unlike the ball model) to detect movement and hence dirt does not get trapped in. The modern ones use laser light instead of an LED and these give top level performance. TrackBall mouse is one in which a prominent tracking ball that reduces hand movement (thumb and finger alone involved) is provided and functions very accurately. However this type is less common.

The connection modes for mouse are - wireless or wired. The wireless variety requires a wireless receiver that has to be connected to the computer. These are ideal for portables and notebooks. There are two technologies in use bluetooth (with operating range of about 30 to 60 feet) and RF (uses radio frequency and operating range is 15 to 30 feet) Hand orientation may be symmetrical or specific, and the symmetrical one is recommended. Wired mice are connected via electric cables to either the USB or PS/2 interface whereas the wired types require AA or AAA batteries. The bluetooth mouse are similar to most wireless varieties but unlike them, these are connect to the system via bluetooth and therefore do not block valuable USB ports.

The other specifications that need attention are the buttons and wheels. USB and PS/2 ports are the commonly used interfaces. While some mice come with 2 buttons and a wheel for scrolling in the middle, some Mac mice do not have the scrolling wheel control. Some mice are specifically designed and used for gaming purposes alone are available as wireless, wired or Bluetooth. Logitech, Microsoft, Kensington are a few top names that manufacture computer mice.

Wi-Fi and Wi-Max - What’s Wrong With That?

Sunday, May 25th, 2008

The hot new craze in Internet access is Wi-Fi and its soon-to-be big brother Wi-Max. Wi-Fi is a wireless connection that allows users to access the Internet without the computer being connected to a cable. And yes, it’s very convenient. Imagine walking from the sofa to the bedroom with your laptop and never loosing your connection. Imagine the freedom and flexibility afforded schools and office workers. No more ugly bothersome cables to tie you down. You’re free to roam the Internet with your fingers while roaming your home, school or office with your feet. Freedom to move and freedom to surf. Perfect for the individual who is on the go and up to date with the latest technology. You can even have free Internet access at your local coffee shop. Same for airports. What a great idea. Or is it?

What exactly is Wi-Fi? Wi-Fi is a common term that stands for ‘wireless fidelity.’ It simply means that a computer can access the Internet without wires or cables. In other words, it allows one to have a wireless connection to the Internet. It’s like taking a cell phone base station and placing it in your home, schoolroom or office area. Wi-Fi is basically the same type of connection as used to operate a cell phone. It’s a product of convenience as it allows one to access the Internet with a desktop or laptop computer without the need for connecting cables. Moving from room to room with a laptop computer and no cables is a nice convenience although it certainly isn’t a necessity.

How does Wi-Fi work? Wi-Fi is really very similar to your cell phone. Radio signals are transmitted from the computer or Bluetooth device to a wireless router, sometimes called a wireless access point (WAP) or wireless local area network (WLAN). The router then sends the signal to the Internet through a cable modem. So this router or wireless access point is really the device responsible for transmitting the harmful radio waves. Any number of computers or devices can be configured to connect to one wireless router to make Internet connections. The workable distance is about a range of 300 feet or more from the wireless access point while most distances for good connections are maintained at about 100 feet. And, of course there are many variables that can affect this connection. Laptop computers and Personal Digital Assistants (PDAs) are the most common devices utilizing Wi-Fi technology.

Wi-Fi Emits Radio Frequencies Wireless connections emit radio frequency signals, or radiation, just like cell phones, cell phone towers and other wireless devices. Wi-Fi usually transmits its signal at frequencies in the range of 2.4GHz to 5 GHz. Cordless phones often transmit in the 2.4GHz to 5 GHz range, too, and this often causes the cordless phone to interfere with a wireless internet connection to a nearby computer. The Wi-Fi frequency is considerably higher than the frequencies used for cell phones which operate in the 850 MHz to1900 MHz range. This higher frequency allows more data to be carried. However, as we’ll see later, it is not the frequency of the signal that does the damage to our health. So the higher Wi-Fi frequency isn’t really the issue at all when it comes to health considerations.

Wi-Fi Hotspots Now In Schools Wi-Fi has become popular in the home, office, the airport and coffee shops. Many cities are now installing “hot spots” where one can take a laptop computer and freely access the Internet over the provided network. This is what is known as a “hot spot.” It’s a place to make a wireless connection to the Internet. And they are springing up everywhere. Entire cities are becoming wireless allowing one to connect to the Internet from anywhere in the city. And due to the ease of convenience Wi-Fi connections in schools are now becoming quite popular, too. No longer are computers hard-wired to a connection in a classroom. Connections are now virtual and allow the user, student or teacher, the freedom to connect anywhere in the school without the burden of being restricted by cable connections.

Why Wireless Connections Are Harmful There are two potentially harmful mechanisms in which Wi-Fi users, including school children, may be harmed. The first mechanism involves the exposure to radiation from the distance or proximity of the user to the computer monitor. This form of exposure originates from the electromagnetic field being given off by the monitor itself and has nothing to do with the wireless connection. Electromagnetic radiation is given off by the computer screen regardless of whether the connection is wired or wireless. Any and all computer screens produce electromagnetic radiation. These electromagnetic fields can be substantial in strength and can reach levels much higher than the 1 milligauss (1 mG) threshold level of exposure recommended by experts as being safe. Such a field can easily be measured with an inexpensive instrument called a gauss meter.

The second mechanism of harm comes from the radiation or radio wave itself. The wireless signal, oscillating at 2.4 to 5 GHz, moves much too fast for the body to recognize. So this wave isn’t doing the damage. However, anytime any data or information is transmitted, say through our voice, through text messages or through the sending of information, the data is packaged and “piggy-backed” onto the first wave. This creates a second carrier wave and this wave is called the information-carrying radio wave, or ICRW. It is the information-carrying radio wave that is producing the harm. Here’s how this happens. This second carrier wave, or ICRW, oscillates in a much lower Hertz (Hz) range that is easily recognized by the body. When the ICRW comes in contact with the body the body recognizes this wave and responds to it as if this carrier wave were some type of foreign invader. When this happens certain physiologic changes occur which are very significant. First, at the cellular level, the cell membrane becomes hard and inflexible. This occurs because the active transport channels shut down as the cell goes into a protection mode. This hardening effect of the cell membrane also causes the cell to lose its permeability, meaning needed nutrients can’t get inside the cell where they are needed. In other words, the cell doesn’t get nourished. Conversely, since the cell membrane is hardened and less permeable, the toxins and free radicals that build up inside the cell, as a natural part of our daily metabolism, can’t get out. The buildup of toxins and free radicals inside the cell causes other problems. These toxic products damage the mitochondria in the cell. If you’ll remember from biology class the mitochondria are where energy for the body is produced. When this energy-producing process is damaged the cell begins to lose its ability to function. In addition, cells lose their ability to communicate with one another. When one cell can’t communicate with another cell and messages don’t get sent or received the body can’t respond properly to any type of stress, injury, or invasion. Furthermore, the DNA inside the cell becomes damaged. Fragments of DNA break off and form something called micronuclei. Micronuclei are precursors to cancer formation. And when enough energy is lost and when enough malnourishment occurs the cell eventually becomes dysfunctional and dies. When enough cells die the tissues are affected. When enough tissue is affected organs become damaged and don’t work properly. And the cascade of damaging events begin that can lead to a multitude of symptoms and failure of the body’s defense mechanisms to act appropriately.

The Wi-Fi Problem Think of Wi-Fi this way. It’s really nothing more than a small version of a cell phone tower placed in the classroom or office. Or, it could be similar to having a cordless phone in your home with multiple handsets throughout the house. The base station is the access point and all the peripheral phones connect with it wirelessly. The radio frequency radiation being emitted is the same. The information-carrying radio wave is being transmitted continuously 24 hours a day. The connections from the computers and other wireless devices throughout the school, office or home to the wireless access points cause any user around them, (children, teacher, staff, etc.) to be continuously exposed. Everyone in the building is caught in the crossfire of the continual access to the wireless access points. Even non-users are exposed because of the blanketing effect of these wireless access points throughout the building. So no one escapes the exposure.

In understanding the danger of Wi-Fi we must remember that it is not the type of device, in this case a wireless access point or router that is important. Rather it is the type of radio frequency radio waves that are being produced by the device that are significant. Whether from a wireless router, a cell phone, a cell phone tower, or personal digital assistant (PDA), electromagnetic frequencies are produced by all these devices. We must look at the technology being used by these devices and not the device itself as the problem. This should be the primary concern as we evaluate their safety, particularly in the classroom.

Another important aspect of Wi-Fi exposure is that of modulation. Modulation refers to whether or not the signal frequency is constant or pulsed. The new digital cell phones operate on a pulsed frequency, as does all wireless technology. Studies have shown that these pulsed signals are a greater risk than analog, non-pulsed signals. 1

Certainly, by the addition of any type of wireless we are adding to the burden of electropollution we are all currently exposed to. Special consideration should be given to the additional exposure that Wi-Fi technology would bring to those in a classroom, including the instructors, teachers, staff and certainly students.

Children Are More Vulnerable Concern about the increased vulnerability to electropollution by children has valid reasoning. Since the skull bones of the head don’t fully harden until about age 22 the skull bones of a child’s head are softer than that of an adult. A softer head bone translates to easier penetration through the skull and into the head by radio frequency radiation. Furthermore, the head of a child contains more water since the brain is not fully developed. It would make sense then that water will act as a conductor to electromagnetic radiation increasing the possibility of even further damage. And since a child’s brain and nervous system is still developing it only stands to reason that the potential damage would be greater since cells that are in a growing phase are more easily damaged. And finally, exposing children in the elementary schoolroom will add to both the amount of electromagnetic radiation exposure and the accumulated length of exposure over their lifetime that they will be exposed. No one can argue that the children of today’s generation will be exposed to far greater amounts of electromagnetic radiation and will be exposed to it for a much longer period of time than any generation before. We simply don’t know the consequences of this increased and cumulative exposure. And it’s an experiment that we shouldn’t place our children in. Why set up these networks without understanding any of the long-term consequences? Did we not learn a lesson from the tobacco and asbestos industries?

Effects of WirelessRadio Frequency Radiation Although no studies have been done on Wi-Fi per se there is a generous amount of research that has been carried out on cell phones, cell phone towers and masts. Since the Wi-Fi signal is the same type of radiation (only the frequency is different) one can assume with reasonable assurance that the effects of exposure to Wi-Fi will follow the same pattern of exposure to cell phones and cell phone towers.

Here’s an example of what can happen. Let’s say one works in a schoolroom or office where wireless access, or Wi-Fi, is used. In other words, we are continually exposed to a constant bombardment of electromagnetic radiation waves. Over time, sitting or working in this classroom or office, the cells of the body gradually loose their energy and consequently their ability to communicate. What if the function of a particular group of cells was to maintain the integrity of the blood-brain barrier? The blood-brain barrier is an intricate membrane that keeps harmful substances and toxins from contacting sensitive brain tissue. But what if the cells of the blood-brain barrier can’t communicate or don’t work any longer? The barrier would break down and this would allow harmful substances to enter. Those substances would then come in contact with sensitive brain cells. The result would be injured and damaged brain cells. This is just one example of how a particular group of cells can be adversely affected by electromagnetic radiation. In fact, studies have shown that placing a call on cell phone for just two minutes can disable the blood-brain barrier. 2 The same case could be made for the immune system and any other major “system” of the body since different cellular groups perform different functions to keep us healthy.

There are more than a dozen studies linking an increased risk for brain cancer and acoustic neuroma (tumor of the auditory nerve) to radio frequency radiation from cell phones and cordless phones. 3

Even the World Health Organization (WHO) is concerned about the effects of radiofrequency radiation on children’s health. In a recent WHO publication they wrote:

“The possible adverse health effects in children associated with radiofrequency fields have not been fully investigated.”

“Because there are suggestions that RF(radio frequency) exposure may be more hazardous for the fetus and child due to their greater susceptibility, prudent avoidance is one approach to keeping children’s exposure as low as possible.”

“Further research is needed to clarify the potential risks of ELF-EMF and radiofrequency fields for children’s health.”

Neurobehavioral effects of inhabitants living near a cell phone tower base station have also been studied. The following neuropsychiatric complaints were reported: headache (23.5%), memory changes (28.2%), dizziness (18.8%), tremors (9.4%), depressive symptoms (21.7%), and sleep disturbances (23.5%). 4 In addition, tests of attention and short-term auditory memory were significantly lower in the exposed participants than in control groups.

Obviously, people living close to cell phone towers have an increased risk for developing neurobehavioral problems.

Will We Medicate Our Children Unnecessarily? If indeed neurobehavioral symptoms are produced by radio frequency radiation and these frequencies are continually emitted throughout our schools what might this suggest about the abnormal behavior of students in the classroom? Might parents be inclined and persuaded to medicate their children so that these undesirable symptoms can be controlled? If so, how many of these children would be medicated unnecessarily? Studies now show that the frequencies such as that emitted by cell phones cause abnormal brain hyperactivity. Such artificially induced hyperactivity would cause an unnecessary risk and expense to students who would be placed on some form of pharmaceutical intervention to aid in controlling these symptoms. Many of the drugs used in controlling hyperactivity, such as Ritalin, Concerta, and methylphenidate are in the amphetamine-like class of pharmaceuticals. What a tragedy it would be to find out years later that this form of medication was unnecessary and could have been avoided if we would have chosen precaution over convenience.

Learning Issues As discussed earlier, the mechanism of harm caused by electromagnetic frequencies occurs at the cellular level. The eventual outcome of this harm is disruption of cell-to-cell communication. When the disruption of cell communication occurs cells can’t “talk” to each other. When cells can’t communicate cognition is affected, the ability to learn is affected, the ability to retain information is affected, and behavioral problems can occur.

Makes Kids Susceptible To Other Stressors Radiofrequency radiation is also a stressor to the body. The mere fact that the cells of the body react to these frequencies as discussed earlier indicates that they are harmful. When the stress response occurs from exposure to electromagnetic frequencies the body responds by releasing stress proteins, also known as heat shock proteins, to minimize the ensuing damage. The release of heat shock proteins is just one stress response mechanism that has been identified. Other mechanisms include the triggering of adrenal hormones like adrenaline. Continual stress is not healthy as it can eventually fatigue the adrenal gland, suppress the immune system, and lead to fatigue causing difficulty in concentration. Sleep disturbances may also occur.

Immune System Affected Evidence also exists that radio frequencies produced by such devices as cell phones, Wi-Fi, computers, televisions, etc. can trigger skin reactions.5 Microwave frequencies can trigger the release of chemicals from mast cells. Mast cells in the skin will break open and release chemicals that cause the symptoms of allergic skin reactions. 6 One of the chemicals released by mast cells is histamine. Histamine is often responsible for the symptoms of allergies such as runny nose, watery eyes, inflammation and difficulty breathing. Histamine also constricts the airway leading to or worsening the symptoms of asthma. It is of interest to note that the rate of asthma in children has doubled since 1980 and asthma now affects one in 10 children. The cell phone was introduced in1983 and has seen explosive growth in use in the last decade. Could there be a correlation between the rising rates of asthma, an immune system problem, and the escalating use of cell phones and wireless technology? Certainly, one could anticipate that chronic exposure to these radio waves over time can lead to chronic inflammatory responses.

Electromagnetic Radiation Connected To Autism A recent study has now suggested a direct link between autism and electromagnetic radiation. It appears that EMR may accelerate autistic spectrum disorders. 7 It is noteworthy that the increasing rates of autism parallel the growth of the cell phone and wireless industry. This appears to occur as a result of the trapping of heavy metals within the cell and the inability of the body to excrete the toxic metals present that are often introduced into the body through vaccinations. Heavy metals are neurotoxic. When this excretory process is prohibited these heavy metals, such as mercury, lead, beryllium, and aluminum, damage nerve structures and interfere in inter-cellular communication. This leads to neurological problems and conditions like those found in autism spectrum disorders. This particular study has shown that when electromagnetic radiation is largely eliminated the efficiency of heavy metal detoxification and removal was dramatically increased. In other words, the body was able to excrete and eliminate heavy metals when it had not been able to do so previously. This leads to the suggestion that (1) we need to reduce or eliminate electromagnetic radiation from any child’s environment and (2) measures need to be taken to repair the damage that has already been done by electromagnetic radiation. Although this study looked specifically at autism the same case could be made for attention-deficit disorders and related conditions.

Occupational Hazard For Teachers And School Staff Children will attend school in a particular building for a finite number of years and then move on. For a child the length of time spent in a particular building or location is predetermined. Therefore their exposure levels to this form of radiation will probably change. But what about the teachers and staff members who continue to work in the same building for many, many years? For these workers and teachers the exposure in their building from Wi-Fi networks and radio frequency radiation is continual. What are the effects of this exposure after years and years of time? Will teaching in a Wi-Fi enabled school become an occupational hazard like that of an electrician? These are questions that must and should be answered before, rather than after, any installation of radiation-generating equipment is placed in service.

Wi-Fi In European Schools The European Environment Agency is calling for immediate steps to be taken to reduce exposure to Wi-Fi, cell phones and cell phone towers and masts. Recent international scientific reviews have concluded that electromagnetic radiation safety limits are “thousands of times too lenient” and one official British report came to the conclusion that the development of cancer from cell phone use could not be ruled out.

Sir William Stewart, chairman of the Health Protection Agency in the UK, is calling for a formal investigation into the hazards of using wireless networks in schools. He’s asking that students be monitored for health problems from the networks. Joining him in health concerns over Wi-Fi installations in schools, the Professional Association of Teachers are calling for the Secretary of State for Education in the UK to begin an official inquiry into the issue.

Recently, parents of children at an English school have won a major battle in getting a mast tower removed from their school. Parents indicated that both students and staff complained of symptoms such as insomnia, headaches and numbness. It seems 56 percent of children had trouble sleeping, 54 percent developed headaches and migraines, and 46 percent reported dizziness and numbness. 86 percent of staff members had problems sleeping, 59 percent reported headaches, and 95 percent of staff reported fatigue and numbness. Nosebleeds, nausea, and dizziness were also reported. 8

Dr. Gerd Oberfield, head of environmental health and medicine in the province of Salzburg, Austria, calls the installation of Wi-Fi “dangerous.” In fact, the government in Salzburg has been advising schools not to install Wi-Fi for well over a year now and is considering a complete ban on Wi-Fi networks.

Stowe School in Great Britian recently removed its Wi-Fi equipment from its building. One of its schoolmasters who had taught there for 28 years developed headaches and nausea immediately after Wi-Fi was installed.

International Association of Fire Fighters In 2004, the International Association of Fire Fighters (IAFF) voiced its opinion on cell phone towers and antennas by opposing the installation of cell phone antennas on or near fire stations until a credible study can be done to establish their safety. In studying the available science the IAFF found over 49 references that led them to conclude that they should oppose the placement of cell phone antennas on fire stations. Some of the effects that have been documented by fire fighters include slowed reaction times, sleep deprivation, severe headaches, lack of focus, tremors, and vertigo. 9

What About Wi-Max The latest development in the world of digital communication is something called Wi-Max. Wi-Max is intended for use as a network for large metropolitan areas. Where Wi-Fi is limited to a range of about 100-300 feet, Wi-Max can provide broadband wireless access up to 30 miles from fixed base stations and 3-10 miles from mobile base stations. It’s been described as Wi-Fi on steroids. It’s used in much the same way as Wi-Fi and will soon become the standard for Internet access. Imagine the implications. Whole metropolitan cities blanketed with Wi-Max wireless coverage. How convenient and “connected” do we really need to be?

Conclusion We currently have no studies that are specific to Wi-Fi. However, when assessing the safety issue we can and should look at technologies that are similar and relevant to Wi-Fi to draw our conclusions. This would seem appropriate since Wi-Fi operates in the same manner as other more heavily studies similar technology and the basic mechanism of harm from all wireless technology is the same.

There are countless reports and studies raising caution signals about the effects on human health from exposure to cell phone radiation, cell phone towers, Wi-Fi, and wireless technology in general. The fact remains that wireless technology is a potential carcinogen. So was tobacco. So was asbestos. So were X-Rays. Like these other hazards, which were all at one time only “potential carcinogens,” wireless technology needs further study before we decide to randomly subject ourselves and our children to the potential harmful effects it seems to cause. How long will we wait for these studies? Another 20 years or more? How many lives will be adversely affected or lost while we take the wait-and-see approach?

What can you do? Don’t let your children use a cell phone. Don’t live near a cell phone tower. Don’t use wireless Internet connections or cordless phones in your home. Provide good nutrition to your children in the form of lots of fruits and vegetables. Everyone needs lots of antioxidants to protect themselves from the free radicals being produced by these high levels of radiation. Good quality water is a must, too.

Get involved in your child’s school. Get on the school board. Ask questions regarding the use of Wi-Fi in the school. Object to the installation of such equipment if and when the possibility is discussed.

School districts today are under ever-increasing financial pressures. Healthy lease money is being provided by the wireless industry to install cell phone antennas on school buildings. Once again, this is an unneeded and unnecessary exposure risk for our young people. Does the extra income provided by the wireless industry outweigh the potential risk to our children? The studies say no and we as parents and responsible citizens need to convey that message to our school boards and legislators.

Two-time Nobel Prize nominee, Dr. Gerald Hyland, a physicist, had this to say about cell phone towers. “Existing safety guidelines for cell phone towers are completely inadequate. Quite justifiably, the public remains skeptical of attempts by government and industry to reassure them that all is well, particularly given the unethical way in which they often operate symbiotically so as to promote their own vested interests.”

3 Easy Steps To Save Money On Your Business Mobile Phones

Friday, May 23rd, 2008

Every company no matter how large or small, needs to make sure they save money. One way to do so is by making sure you aren’t over-paying with your business mobile phone tariff and compare business mobile phone contracts that are available.

Your companies circumstances can change from one month to the next, so when you sign up to your initial business mobile phones contract, it doesn’t necessarily mean that will be the best one for the life of your company. You may grow in size over the coming months, or maybe you have to reduce the number of employees you have, whatever the circumstances, it is worth re-evaluating your business mobile phone tariff whenever it is due for renewal.

Step 1: Analyse

Look at the contract for your current business mobile phones. What kind of tariff are you on? Are you utilising all the features you are paying for? Maybe you signed up for 300 minutes per month but find you are only using half of these, or maybe you thought you would need the video conference option, but are in fact paying for something you don’t need. Do you need all the handsets you have or can you cut down? Maybe you are employing someone new and require more handsets. Either way, just by analysing your phone tariff and contract, you will probably find you can save money.

Step 2: Compare

The next step is to compare tariffs on mobile phones for business with all the major networks. This may involve phoning them up and asking a series of questions, going into mobile phone shops or finding all the information you need on their website. All the websites should have their current price and tariff information online as well as details about the handsets they stock and what features they have.

Step 3: New or Renew

Your final step is to actually take action and decide whether to renew with your current mobile phone supplier or move your business to another network. You may choose to contact your current provider and explain you want to change your contract or tariff details and see what options they can offer you. If you still aren’t happy you may find you want to change to a provider who will give you a better deal on your business mobiles phones and save your company money.

The contract you have for your company will depend on what work you do, and what requirements you have. Some businesses may require a handset for each employee to make calls on in order to do their everyday work. Others may need handsets that are hardwearing, come with or without a camera, are bluetooth enabled, come with a hands-free kit or have a set number of minutes per month. No matter what your requirements, most mobile phone networks will be able to offer whatever you need.

In order to save you time and money, there are websites that will do the time-consuming comparison for you. By entering a few simple pieces of information online, they will be able to search through all the major mobile networks and find a cheaper, better tariff that suits your needs, before getting back in touch with you.

Stretch and Stay Flexible For a Good Golf Swing and Lower Golf Scores

Wednesday, May 21st, 2008

A good golf swing is a combination of comples body movements that involve almost the entire body. As we get older or more sedentary we lose muscle tone and flexibility. If you are not involved with a regular exercise routine you muscle will shorten and your joints will tighten up. Come the weekend and you want to head to the local course you will find that your performance is less than desired. Many golfers will take a bucket of balls and try to loosen up and revive muscle memory. This is a good Idea as it acts a warm up and will prevent injury out on the course. In order to maintain or improve your golf swing you should be exercising days before you head to the range or course. Remember if you have a choice between strength and flexibility when playing golf, flexibility is much more useful and preferred.

A good golf swing comes from flexibility and flexibility comes from stretching.The goal is to lengthen the muscles and loosen the joints. You should start by flexing and rotating all of your joints. Start with your wrists by rotating them first to the left then to the right. Interlock your fingers and place your palms facing away from you and stretch your fingers. Shoulders are a major player when it comes to making a good golf swing. Raise your arms out in front of you and begin to make small circles with your hands. Slowly move your arms out to the side continuing to do the shoulder rolls. Rotate your arms as far to the back as is comfortable then reverse the rotating and start moving the arms back to the front. The exercise should be done slowly and only requires on repetition.

Your head and neck are also an important part of your golf swing. A flexible neck will add to your swing speed while help you to maintain the proper swing plane. Stand straight up and slowly roll your head to the right 3 times and then reverse the process to the left. Next take you right elbow and place it straight up next to your head then grasp it with you left hand and pull straight to the left holding it for 6 to 10 seconds. Then reverse the process stretching the left shoulder.

Every golfer knows that the power of a good golf swing comes from the hips. Find a broom or long pole and place it on your shoulders just behind the head. Extend your arms out in each direction reaching as far as you comfortably can. Stand with your feet about shoulder width. Next turn your torso left as far as it will flex using your hips only then swing back the other direction for at least ten repetitions. Do not use your arms to force the rotation. Remember not to lead the rotation with your shoulders. You must keep your arms quiet during this exercise. A power body rotation comes from the hips to the chest into the shoulders. You wind up your torso like a spring and then let it unwind smoothly.

Stretch your hamstring muscles by standing with your feet slightly wider than shoulder width and slowly bend down reaching for the floor. Take your time and when you have reached about as far as you can go let your body weight just hang there stretching your back and hamstring muscles. Keep your legs straight. Do not bounce your weight up and down. After about ten seconds stand up straight and slightly arch your back. Then turn slightly to the right and reach for your right foot slowly stretching. Repeat the movement to the left each time straightening up fully before making an extension. You should do between 6 and 10 repetitions of this stretch.

One additional stretching exercise that will help you develop a good golf swing is called the chair squat. Stand behind a sturdy chair that has a good back to it. Again your feet should be about shoulder width. Place you hands on the top of the back of the chair and slowly squat down until you upper legs or hamstring muscles are parallel with the floor. Do not go down any further. Keep your back as straight as possible with your head up. Then stand up again slowly. If your legs are too weak to handle the weight of your body use your hands on the back of the chair to help lift your body. Your goal should be to do at least 10 to 20 repetitions. This exercise will not only increase the flexibility of your legs but also your hips and back.

You should plan on doing your golf swing flexibility exercises at least three days a week. Your flexibility and strength will increase each week. The beauty of this exercise routine is that you can almost do it anywhere even in your office or at home. Maximum benefits appear in about 5 to 6 weeks. You will be amazed at how much stronger and more flexible you will be and how much your golf swing has improved. Your handicap and scores will be lower and the game more fun. A good strong flexible body means you will have a better chance of developing a good golf swing and lowering your golf Scores.

Warrior Golf - How To Play - Volume II

Tuesday, May 20th, 2008

Do you think about leaving the golf ball below the hole when you plan your approach shots? The pros do…you should too. Why leave yourself a tricky downhill putt? Give yourself the best chance to par the hole, or even better, birdie the hole!

If you’re playing a dog leg right (the hole curves to the right) and you’re a right handed golfer, tee the ball on the right side of the tee box and aim for the left side of the fairway. This one strategy improves your angle to the hole and actually widens the fairway for you. If you push the ball right you will still be in the fairway because you were aiming left. Since you are hitting from the right side of the tee box, you will really have to miss left to be in trouble because you are using the whole width of the fairway.

You want the ball to end up on the left side of the fairway ideally for the best angle to the pin on a dog leg right. Just reverse this logic for dog leg lefts. Think smart and play golf like a warrior when you are on the golf course and watch your scores plummet!

Do you always go for the pin on your approach shot to the hole? There is a time for being aggressive, say when your 3 down with 4 to play. However, if you want to give yourself the best chance of shooting your best score, most times you want to aim for the center of the green…especially when the hole is tucked in a corner surrounded by water, rough, and bunkers.

Read on for some pop golf psychology…

Here’s a psychological technique Tiger likes to use when he’s in match play. Whether you’re playing with your regular golf partners or you are in a match play tournament, try this… Let your opponent out drive you so you can shoot first to the hole…hopefully you left yourself with your “sweet spot” distance from the hole that you can execute in your sleep. Then knock it on the green! This puts extra pressure on your opponent and he/she will probably hit a wayward shot…try this…it works!

Here is another psychological technique to use on an opponent who is trying to rattle you with gamesmanship. Just as the smart aleck is planning the shot, make an innocent comment about any trouble on the hole….such as: “boy, look at how the sun is reflecting off that water hazard out there!”…I guarantee you this; the water hazard will be the last thought in the knucklehead’s mind before he/she swings. :)

Play golf like a warrior…survey the golf course…plan ahead and play within your limits and your golf scores will fall like so many opposing soldiers on a battlefield!

Make Sure that Your New Product Will Make Money BEFORE You Put Your Life Savings on the Line!

Sunday, May 18th, 2008

You have to really evaluate your new product or service you are introducing to the world in a very realistic fashion. I know that most of your friends and colleagues are extremely excited about your new business venture, but a full eighty percent of new businesses fail within the first six months of start-up.

The only way to avoid becoming the next sad statistic in the business world is by evaluating the viability of your product idea as well as other factors such as market competition, the marketplace demand for your product as well as making sure you have the right people in your organization that will help your product succeed in the cut-throat corporate world.

RESEARCH EVERY SINGLE DAY The amount of research you put into examining the market you are trying to enter your new product into will payoff huge in the long run if you utilize the proper research tools. If your new product is a line of computer software that will help homeowners secure the best interest rates when they acquire a second mortgage, for example, you really need to examine the finance market and determine how many other companies are already selling software that includes this same financial function.

I would start off by doing a Google search by inputing the phrase “homeowner finance software” into Google’s search box. This will allow you to not only examine the individual software that is already on the market, you will also be able to see what websites are in business selling financial software as well.

Your research needs to take all of these factors in consideration because if there are too many sites that are selling this particular software, there may be no need for yours unless your new product is either much cheaper in price, or it is a lot more user-friendly than any other piece of software on the market today.

TAKE AIM AT YOUR CUSTOMER BASE AND FIRE AWAY! You must locate your target customer base and ask them individually what they would love to see in a new product or service that you are currently attempting to bring to the marketplace. Stay away from friends and relatives who might be biased, and take an informal internet survey from strangers instead. There are a lot of market research companies that have websites where you can place an order requesting your own market research to take place based on what you believe your future customer base will be.

For a fee, one of these market research companies will compile a list of questions based on what you need to know from your customers that they will then send out for these customers to answer within a few weeks time. When the research data comes back, you will have a more exact description of just what your potential customer base needs to see in your new product for them to want to buy it in the future.

MAKE SURE YOU LEAD WITH YOUR BRAIN, NOT YOUR HEART When you invest your time and money into developing a new product or service, you are actually gambling with your future, so you must make sure that you are not allowing your feelings to mislead you at any time during this critical time period of starting your own business. By instigating great research, locating a specified target customer base for your new product that will actually want to buy it, your future success as a new business owner will be assured.

Computer Addiction: Social and Multimedia Surfers

Saturday, May 17th, 2008

More and more people find themselves facing a difficult situation with computer addiction. It’s an addiction that’s shared by young and old, and now strikes as many women as men, as many young people as retirees, and people from every education and intellectual level. Different groups are more likely to be struck by different types of addictions, but there’s plenty of computer addiction to go around.

Online Social Networking

The first group that’s likely to get hooked are folks who have difficulty with social situations. They may be shy, insecure, and find the computer a desirable way to be able to interact with large groups of people without having to physically be in their presence. The old Internet joke that “no one knows you’re a dog” may make some people smile, but for socially challenged folks, being able to develop relationships with people from around the world is no laughing matter. There’s a certain safety on the Internet that raises people’s self-confidence without having the stress of face-to-face encounters.

Multimedia Stimuli

However, it isn’t just socially challenged people who find themselves addicted to the computer. The latest breed of computer addicts are people who like to lose themselves in multimedia presentations and the sheer color and glitz of the World Wide Web.

It’s no longer necessary to have any real computer training to get on the Internet and surf to your heart’s content. All you need is a modem and a browser, and you’re off and running. That means millions more people are surfing, which brings with it the potential for an exponential increase in various computer addictions.

Monitor your computer use. If you find that you’re spending more time interacting with people online than in person, perhaps it’s time to get some help with computer addiction.

Tennis - Are You Afraid To Lose?

Thursday, May 15th, 2008

Are you technically a great tennis player, but somehow, always seem to lose to players of lesser abilities? If so, it sounds like you’re afraid to lose. Don’t worry, you’re not the only one experiencing this. I too, struggled with this problem as I was also “afraid to lose”. Here’s what happened. As a junior, I was able to out perform any other tennis player when practicing drills or playing practice matches. However, during tournaments (when the match actually counted), instead of driving the ball through the court, I would tighten up and start “pushing” the ball over the net. Why? Simply because I was afraid to lose. As a result, players below me who had nothing to lose were able to occasionally pull off the upset against me.

This is what separates the top players from the rest. Top players are able to play through the pressure with out the fear of losing. Eventually, I was able to train my mind to forget about losing and to focus on winning. After I mastered this, my game really took off and I gained a tremendous amount of confidence.

Here are some tips to deal with your fear of losing:

* Focus on where you want to hit the ball, rather than focusing on not missing

* Concentrate on your footwork rather than your strokes

* Create a goal for each point, and focus on that. A goal can be to serve and volley or to angle your opponent off the court. It can be anything.

* It is impossible to make every shot and to win every point. You are going to lose some and win some, but if you play without the fear of losing, your results will be much better, guaranteed!

* If you know that being afraid to lose makes you play worse, why do it? Swing away!

* The first ball you successfully FORCE your self into swinging freely will make the next few balls you hit become more and more natural(so you wont have to force it).

These are just a few tips that helped me get past my fear of losing. By focusing on something else, it took my mind away from losing. Not surprisingly, it translated into more winning.

The Amazon Kindle - The Ultimate Ebook Reader?

Wednesday, May 14th, 2008

The Amazon Kindle is relatively new to the market and is one of a growing number of ebook readers available to us today as a result of the growing popularity of ebooks. However, there is a little something different about the Amazon Kindle Ebook Reader that sets it apart from the rest. There is most definitely something that makes it special but it is difficult to put your finger on. The reason why it is so difficult to identify just why the Amazon Kindle captures your attention is because there is no one reason. Instead, there is a whole host of them!

The Amazon Kindle is an amazing piece of technology that allows you to read books and keep up with your news and favourite blogs at the same time. The daily blogs and newspapers are updated every single day via a wireless connection so you do not actually have to go out and physically look for the information you want! It is right there! The wireless connection always works because of the nature of the Amazon Kindle technology. They also take care of the wireless bills so that you have no further cost… other than the books you buy of course!

If the Amazon Kindle actually provides all of this, you may put forward the argument that you can get it from any computer. However, you would be missing the point. The Amazon Kindle is not a computer. It is a portable ebook reader that does not even resemble a computer. You can use it wherever you want to and still receive updates, regardless of whether you are in or near a hot spot or not!

In many ways, the Amazon Kindle is the ultimate ebook reader, but to see just how far that statement holds true, you will just have to try it for yourself!

Could Computer Rental Benefit Your Business?

Monday, May 12th, 2008

In today’s increasingly technological world, the need to drive your company forward is always at the top of the agenda, whether it be the advancement of your operational systems, requiring staff training; an informative conference for your customers; or your company’s presence at an exhibition - it’s an absolute necessity to have the equipment and resources to fulfil such requirements . But for many companies, the resources are not always at hand and the cost of buying both IT and Audio Visual equipment for such short term events is not economically viable. Thankfully, though, there are a variety of options that can help businesses reduce this significant cost - the most popular of which is computer rental.

Whether you’re a small company trying to advance both your company and staff or you’re an established business looking for tax efficient solutions for your short term needs, opting for computer rental lets you free up valuable capital that you can then invest in resources that will aid both the growth and security of your company. Moreover, modern computing and audio visual technology tends to depreciate in value relatively quickly. Renting these facilities will eliminate the costly implications of having to replace obsolete machinery, helping you maintain what’s most important to your company: a healthy bottom line.

Computer hire can also benefit businesses looking to improve or implement a carbon footprint policy. For instance, if your company is entering into a recruiting process where the expertise/applicants are predominately abroad, you could freely target a geographical area and reduce the need for travel by hiring video conferencing equipment; and it isn’t just talking to people abroad, the need for live visual links within the UK are growing by the minute.

Additionally, if you’re in the process of moving offices or you’ve just opened up a new department in your existing office, computer hire may provide you with a comprehensive solution when deciding where best to allocate resources. For instance, if your new office is plagued by a leaky roof, hiring computing facilities allows you to devote your resources towards getting the roof fixed.

If you’ve got members from another branch of your business coming to visit for a few days, but you’ve got no free computers available, renting computers will allow you to make sure they’re able to continue with their work in your office in comfort - an advantage that can be particularly beneficial in the event of a broken or stolen laptop! When hiring IT and AV equipment you are also obtaining added value services such as technical planning/guidance and more importantly engineering support throughout the duration of the hire period - removing the strain on your own resources with the added bonus of not incurring costs.

Essentially, computer hire facilities can make a big difference to your business - in terms of profitability and making sure that your company has the right resources for every requirement. Furthermore, many computer rental companies don’t let rental payments become affected by changes in interest rates, thus letting you plan the future of your business with greater certainty. And as the cost of hiring computers and IT equipment can be deducted from your taxable profit, thereby reducing the net cost, so there’s really no reason why computer hire shouldn’t work for you.
