Does Your Computer Impact Your Health?

We cannot deny the fact that our life today is made of web chatting, navigation, PC games and the list is endless. Some spend hours and even days without moving from the front of the computer; shower and food are skipped and only physiological needs force them for a few seconds out. But do you think that so much staring at a computer screen does not affect you? Here is just a part of the effect: the “computer vision syndrome” comprising tired dry eyes, blurred vision, eye strain, headache, and sensitivity to light.

A recent survey made by American Optometric Association, on about 1,000 persons older than 18, revealed that 82% used frequently the PC; 42% spent over three hours daily in front of a computer screen; 73% did not take computer breaks as often as recommended; 10% did not take breaks at all.

Protective measures

“First, get your eyes checked regularly and work with your doctor of optometry to solve these problems. The doctor who knows you are using a computer for an extended period of time will do things differently for you then they might otherwise do. Special computer glasses and computer screen filters are available to help reduce glare and eye discomfort,” said Daum.Don’t forget to blink.

Daum explained that we sould remember to blink when using a computer. When we concentrate, our blink rate goes down, leading to dry eyes. Every 20 minutes look away from your computer for about 20 seconds; this will minimize the development of eye-focusing problems and eye irritation caused by not blinking enough.

Work space lighting is a crucial issue. The amount of lighting at the office must be lowered, by replacing a bright light for an overhead light, or use a dimmer switch for controlling the degree of room lighting.You should not see any glare or reflection at all off your computer screen. You should not have windows in your field of view.You should also be careful about the ergonomics of your computer. The screen should be right in front of you so you don’t have to twist to see it and the monitor should be right about eye level or a little below eye level.

Home Gyms to Fit Any Space

They’re convenient, surprisingly cheap, and you don’t have to shower other men…

If you think of your home as the ultimate in sports entertainment, then the thought of working out there is probably the lamest of reasons you call it so. Let’s face it: Exercising at home isn’t exactly as appealing as having the guys over for a 24-hour, beers-a-plenty ESPN-Star Sports-Viva Vintage festival.

Such an experience could provide stretches as predictable as Ferrari’s recent regular 1-2 finishes, sure, but overall (especially when the great saint San Miguel’s around to inspire you) everything would turn out be exactly as it should – what whit beer bottles disguising themselves as bowling pins, pals using cold squid balls for putting practice, and your executing the Stone Cold Stunner on a friend who forgot to chip some money in.

Then the next morning comes. You look at how thrashed your den has become and you wonder whether cleaning it all up is even close to what a thoroughly invigorating and well-earned workout means. You literally perspire beer, a punishment so offensive to any human being within smelling distance. This has to stop, you say to yourself. Finally, you decide to sweat it out their right away – in the very comports of your just restored, orderly home.
Building home gyms has its unique advantage. You can watch TV shows with the volume adjusted to your liking, listen to crisp-sounding, original CD’s, familiarize yourself with your own equipment, and get your- swear-a-second mouth into high gear to motivate yourself. Most important, because of the home-base set-up, the likelihood of your fitness resolution morphing into an amnesiac Jason Bourne will be halved.

Space isn’t that much of a consideration because you’ll do away with large equipment in this set-up, anyway. What you really need here is an elastic rubber tubing around two to two-and-half meters long. Your favorite drugstores definitely sell it. Junk any thoughts of using the tubing for purposes that can get you a gig at DARE, please. With it, you can effectively chip away excess fat and fortify muscles depending on the resistance and strength of the tubing you use. WHAT EXERCISE YOU CAN DO? Chest press, bicep curls, triceps extension, preacher curls, squats, calf raises, leg extension, leg kickbacks and shoulder press.

Obesity, Diets, Diet Pills and Exercise

Theoretical facts is that individual who are overweight or obese run a greater risk of developing diabetes mellitus, hypertension, coronary heart disease, stroke, arthritis, and some forms of cancer. The body mass index (BMI) is commonly used to determine desirable body weights.

BMI is a measurement of an adult’s weight in relation to height, and it is calculated metrically as weight divided by height square (kg/m2). People with BMI of 25.0 to 29.9 are considered overweight and people with BMI of 30 or above are considered obese. Do compute your BMI.

Body mass index only provides a rough estimate of desirable weight, however. Weight alone may not be indicator of fat, as in the case of a bodybuilder who may have a high BMI because of a high percentage of muscle tissue, which weighs more than fat. Likewise, a person with a sedentary lifestyle may be within a desirable weight range but have excess fat tissue. In general, the higher the BMI, the greater the risk for developing serious medical conditions.
Studies have shown that meal replacements are often more effective than very low calories diets, resulting in an increase in the amount of initial weight loss and enabling dieters to maintain their weight loss. Regarding diet pills, it would only take over a sex month period that weight loss medication may result in a 10-percent body weight reduction. Weight loss slows or stops after six months, and discontinuing medication usually causes weight regain. However, the continued use of diet medications keeps most of the lost weight from returning for two years.

Caloric restriction alone will not produce long-term weight loss. Research clearly indicates that regular exercise is the single best predictor for achieving long term weight control. Regular exercise will also improve some of the medical conditions associated with obesity, including elevated blood cholesterol, hypertension, and diabetes mellitus. Prevention is better than cure and obesity is preventive.

Oral Sex Boosting Number of Oral Cancer!

This is a little bizarre: while cases of mouth cancers caused by tobacco and alcohol have being decreasing since 1982, due to their lower consume, a new culprit for this type of cancer is causing increasingly more victims: oral sex.

More specifically, a human papilloma virus (HPV), which can be
transmitted through oral sex, causes tongue, mouth and throat cancers, besides cervical, penile and anal cancers. The number of this type of cancers has risen by 33% from 1973 to 2004, as found by a team led by Maura Gillison at Johns Hopkins University in Baltimore, Maryland, US, in a research published in the “Journal of Clinical Oncology.” The researchers used data recorded in the US National Cancer Institute registries, recording about 46,000 cases.

“What we do know is that the prevalence of HPV is high, particularly among young people and this shouldn’t be a surprise given that, since the sexual revolution, people have been having more sexual partners,” Lesley Walker, director of cancer information at Cancer Research UK, told NewScientist.

“The rise was largest among young white males, suggesting this group is more likely to have oral sex at a younger age now than it was 20 years ago. It adds that further research on the role of race and sex, and oral sexual behavior, is needed,” wrote the authors.

“What is not in doubt is the need to consider giving boys the HPV vaccine, to protect them from the disease,” said Gillison.
There is already a Merck vaccine targeting HPV strains responsible for cervical (uterus) cancer in young women and girls. The same viral types are also known to provoke oral, penile and anal cancers. The HPV16 strain is particularly aggressive.
“We need to start having a discussion about those cancers other than cervical cancer that may be affected in a positive way by the vaccine,” said Gillison.

Why Is Oral Sex More Dangerous for Men?

This sexually transmitted virus is more dangerous than all others: it can spread through anal and oral sex, and cause cancer in all it touches, from cervical (uterus) cancer in women to anal and oral cancer in both men and women. The human papillomavirus (HPV) causes now as many cancers of the upper throat as tobacco and alcohol, being correlated to a boost in oral sex practice and the decreasing number of smokers.

There are anti-HPV vaccines on the market, developed by Merck & Co. Inc., but by now they target only girls and young women. Now, it appears that male vaccinations are required for impeding men spreading the virus.

HPV is the leading cause of cervical cancer, which affects around 12,000
women annually in U.S. alone. Mild strains of the virus cause genital warts, but other strains can cause from penile to anal and throat cancer; yet male cases are not given as much attention as in the case of cervical cancer.

A previous study made by a team at Johns Hopkins University determined that HPV is the main cause of annual 5,600 new cases of tonsils, lower tongue and upper throat cancers in US. A new research made by the same team on 30-year data on oral cancers, gathered at the National Cancer Institute, determined the rate of HPV-caused cases analyzing 46,000 registered cases. The incidence levels for HPV-related oral cancers increased steadily in men from 1973 to 2004, matching those caused by tobacco and alcohol.

“The good news is that survival rates for the cancer are also increasing. That’s because tumors caused by HPV respond better to chemotherapy and radiation. If current trends continue, within the next 10 years there may be more oral cancers in the United States caused by HPV than tobacco or alcohol,” said co-author Dr. Maura Gillison of Johns Hopkins University.

Some studies point that not only oral sex can be responsible for these cases; the virus seems to be transmitted to the mouth even by unwashed hands. The study also revealed that HPV-related upper throat cancers dropped in women from 1973 to 2004.

Merck’s vaccine is effective against four types of HPV, one of them connected to oral cancer.

“Merck has been testing the vaccine in an international study, but it is focused on anal and penile cancer and genital warts, not oral cancers. We are continuing to consider additional areas of study that focus on both female and male HPV diseases and cancers,” said Kelley Dougherty, a Merck spokeswoman.

Merck may come with a vaccine targeting men in 2009.

Outdoor Survival Tips!

Nature can supply everything that is essential to survival but the secret isn’t just availability. The secret to survival is knowing what you need, where to look for it and how to use it to your advantage. Keeping this in mind the following material has been specifically designed and organized to answer these questions and supply as many helpful hints as possible about surviving within a wide variety of extreme situations.

DIRECTION:
1. Keeping on course: The great frontier has all but disappeared in America. To find your way out of most forests these days, a person only has to walk a few miles in any one direction. The problem is that a few miles can turn into several days of travel if the course chosen isn’t a straight one.
Tip 1 To avoid any delay in self-rescue simply pick an object in the distance and walk to it. As you approach this object choose another directly in line with the first. By following this simple yet effect formula you can’t help but travel in a straight line.

2. Using your watch as a compass: There are three requirements for this process to work. First your watch must have an hour hand. Second the watch must be set to the correct local time and third the sun must be shining bright enough to cast a shadow.
Step 1. Next to the watch place a thin object (Pine needle or twig) capable of spreading a narrow shadow across its surface.
Step 2. Line up the watch so that the shadow crosses over the center of the 12 O’clock symbol.
Step 3. Calculate the half way point between the 12 O’clock symbol and the hour hand. This is True North. To find True South simply line up the hour hand with the shadow, and find the half way point between it and 12 O’clock.

3. Using a pin or needle as a compass: In order for any survival expedition to be successful, you must have the right materials. To use a needle as a compass, you must have a silk or other type of polarizing cloth. This is all you will be needing (aside from the pin of course!)
a) Rub the needle on the cloth in one direction (it doesn’t matter either up or down. It must be rubbed in a dragging motion IN ONE DIRECTION ONLY!!!
b) Place the now magnetized/polarized needle on a leaf or other such floatable material in a small motionless pool of water. The side of the needle that was dragged across the silk will point North. And that’s how it’s done!

4. The Moss theory: Due to moisture content and sunlight, moss generally grows on the North side of trees. This of course isn’t very dependable because of the various climate conditions but it could be a good collaborator to other methods of telling direction.

5. Celestial navigation: The North star, Northern lights and the suns movements are the oldest means of navigation in the world. Northern lights: Simply scan the night sky and watch for strange cloud type objects moving in the sky just above the horizon. These are the Northern lights. After finding them simply make note of their direction by lining up two land marks in a straight line with the movements of these lights. Rising and Setting sun: The sun rises in the East and sets in the West.

6. Know where was that spot again? Triangulation is simple when using a compass. When your standing in a spot you would like to come back to, take out your compass and face directly toward one of the four main directions North, South, East or West. Now simply move to your left 45 degrees and line up a landmark (remember it), then turn back to where you started and move 45 degrees to the right and line up another landmark. This quick triangulation will get you back to this position within a few feet every time. (Just remember your land marks and original direction chosen, then its a simple task of just realigning them)

~tips for reducing pack weight…

Take time – before, during, & after each hike – to peruse your gear, your packing habits, even the clothing you wear, for ways to reduce the weight that you must bear. You may be surprised at the amount of unnecessary weight that you inflict on yourself. Keep in mind, though, it is a process. A long-term commitment and challenge. You will, undoubtedly, think of something new practically every trip.

Here are some weight-reducing tips some are original, some are commonly known and used.

•3 lb Pack, 2 lb Sleeping Bag, 3 lb tent
This is, perhaps, your biggest opportunity to reduce weight. Seek out a good 3 lb pack that is relatively comfortable with 35 to 40 pounds in it. Since, most of the time, you will be carrying less than that, the suspension of that 3 lb pack should be adequate for you. Get a good 2 lb, 20 degree, goose-down (or comparable synthetic) sleeping bag and a good 3 lb 3 or 4-season tent. Let’s see, 7 lbs minus 3 lbs (pack), 3.5 lbs minus 2 lbs (bag), 5 lbs minus 3 lbs (tent)–that’s a weight reduction of 7.5 pounds. SEVEN AND A HALF POUNDS !!!

•Seek out TITANIUM products
Pots, stoves, backpack stays, tent pegs, anything metal, if made of titanium, will be significantly lighter than any other metal. For example, my titanium cook pot (with lid & handles) weighs 6 oz. That compares to 14 oz. for comparable MSR or SIGG lightweight stainless steel and about 10 oz. for Traveling Light’s Aluminum entry. For stoves, my titanium Primus butane/propane (with windscreen) weighs 3.4 oz, compared to MSR Whisperlite–12.7 oz, and Camping Gaz Micro Bleuet–7 oz. (both without windscreen). So far, in my experience, strength and durability of titanium products seem to be more than adequate.

•Toothbrush / Tooth Powder / Dental Floss / Sewing Kit
Assuming you use more than just your finger to clean your teeth, here’s a tip or two.
First find a toothbrush with a short head, say 3/4 inch. Next, cut off the handle–leaving about two inches to hold onto–and finish it off by sanding-down the rough edges. Oh yeah, drill a few holes in the remaining handle — if it’s a fat handle, hollow it out with your drill. Be creative — don’t forget to show it to me, if we meet on the trail ! :-)

Tooth powder is lighter than paste, and can be meted out much easier. I measure a small palm-full for each day on the trail and store it in a very-small, very light plastic container which resembles a 35mm film container, but is about 1/2 the size and weight.

If you are going to carry dental floss, two suggestions. Take the floss, leave the plastic container behind. Rather than packing a sewing kit, use the waxed floss as emergency thread for gear repair.  Put a sewing needle or two in your first aid kit or somewhere else safe.

•Water Is Heavy
So only carry what you need. Here are two potential ways to reduce the amount of H2o you’re packing (1) If you know the area you’re in and can be sure there are watering holes up ahead, pack only enough to get to the next water hole. Also, (2) if you drink as much as your innards can hold before you hit the trail and at each water fill-up, thereafter, you won’t need to carry as much, after you get going.
I follow these tips and now, most of the time, carry at least one pound less on my back because of it. (Caution: If you alpine scramble or otherwise navigate crosscountry – esp. if you desert hike – you may need to pack it all – plan carefully.)

•About Stuff Sacks
I carry much of my gear in color-coded stuff sacs and zip-loc freezer baggies. Where I use stuff sacs, I adhere to the following. (1) Use the right size sack–wasted space means unnecessary weight. (2) Cut off labels inside sack (3) Allow just enough drawcord so sack can have full opening–cut off the rest and melt the ends so they won’t unravel (4) Use the strongest-smallest plastic cord-locks you can find. All this may seem insignificant, but it adds up after a while.

•Clothes
Cut off unnecessary labels and lengths of cord. If garments have cord locks, replace them with lighter versions, or instead, use small doubled-up patches of light-weight leather with slits. I’ve noticed that some manufacturers have been doing this, also.
If you carry extra clothes for emergencies, cut off pockets, cords, tags, unneeded linings, etc.
I have saved some weight on hats by cutting out labels and replacing plastic adjusting straps with elastic. It feels better and won’t break in the field as easily as the plastic ones.

•Backpacks
Shorten nylon webbing straps wherever possible. I once saved a quarter pound (4 oz) by removing the hypalon crampon patch from the top of my pack’s lid and the nylon belt loop with foam backing from the inside (which allows the lid to double as a hip sack when removed from the pack). In addition, I removed a couple of plastic loop fasteners on the sides of the lid used as part of the hip sack configuration. Most of the time, I don’t need those parts (and their corresponding 1/4 pound !).
For the times I was taking a long trip which included some day-hiking or I needed the heavy-duty hypalon patch, I purchased a second lid.

•Boots, Shoes & Laces
Two tips here. The first, definitely do it. The second, consider it a potential way to significantly reduce relative pack weight, but don’t take it as gospel. Analyze your own situation, experiment, and do what’s safe and healthful.

First, on shoes and boots, I cut off excess shoe lace–for two reasons (1) excess shoelace means unnecessary weight and (2) excess shoelace means safety hazard in the bush. Ever have a big lace-loop catch on an exposed root or tangly bush ? After you cut them, scorch/burn/melt the ends so they won’t unravel.

And secondly, as your pack weight goes down, your requirement for heavy boots is reduced, as well. Since each pound on your feet is supposedly equivalent to 5 pounds on your back, you can reduce the relative weight of your pack by getting a pair of lighter weight boots.
If you have, as one lightweight packer terms it, entered the new paradigm where your pack weight is really low–25 pounds for four or five days–you might even want to consider going with a sturdy pair of 2 pound cross-trainers or running shoes. Like I said, though, there’s potential here, but experiment. What works for me, may not work for you.

Consider the implication. Assuming the “1 pound on the foot is equal to 5 pounds on the back” theory is true, trading-in the 4 pound boots for a pair of 1 3/4 pound running shoes (with vibram soles) would decrease your relative pack weight approximately 11 1/4 pounds ! It’s at least worth a second thought !
