A usefull? guide posted at mohammadi.ca of 18 body trick, everyone should know. Let’s take a look…

1. If your throat tickles, scratch your ear!
When you were 9, playing your armpit was a cool trick. Now, as an adult, you can still appreciate a good body-based feat, but you’re more discriminating. Take that tickle in your throat; it’s not worth gagging over. Here’s a better way to scratch your itch: “When the nerves in the ear are stimulated, it creates a reflex in the throat that can cause a muscle spasm,” says Scott Schaffer, M.D., president of an ear, nose, and throat specialty center in Gibbsboro, New Jersey. “This spasm relieves the tickle.”

2. Overcome your most primal urge!
Need to pee? No bathroom nearby? Fantasize about Jessica Simpson. Thinking about sex preoccupies your brain, so you won’t feel as much discomfort, says Larry Lipshultz, M.D., chief of male reproductive medicine at the Baylor College of Medicine. For best results, try Simpson’s “These Boots Are Made for Walking” video.

3. Feel no pain!
German researchers have discovered that coughing during an injection can lessen the pain of the needle stick. According to Taras Usichenko, author of a study on the phenomenon, the trick causes a sudden, temporary rise in pressure in the chest and spinal canal, inhibiting the pain-conducting structures of the spinal cord.

4. Cure your toothache without opening your mouth!
Just rub ice on the back of your hand, on the V-shaped webbed area between your thumb and index finger. A Canadian study found that this technique reduces toothache pain by as much as 50 percent compared with using no ice. The nerve pathways at the base of that V stimulate an area of the brain that blocks pain signals from the face and hands.

5. Breathe underwater!
If you’re dying to retrieve that quarter from the bottom of the pool, take several short breaths first — essentially, hyperventilate. When you’re underwater, it’s not a lack of oxygen that makes you desperate for a breath; it’s the buildup of carbon dioxide, which makes your blood acidic, which signals your brain that somethin’ ain’t right. “When you hyperventilate, the influx of oxygen lowers blood acidity,” says Jonathan Armbruster, Ph.D., an associate professor of biology at Auburn University. “This tricks your brain into thinking it has more oxygen.” It’ll buy you up to 10 seconds.

Google is preparing its own distribution of Linux for the desktop, in a possible bid to take on Microsoft in its core business – desktop software.

A version of the increasingly popular Ubuntu desktop Linux distribution, based on Debian and the Gnome desktop, it is known internally as ‘Goobuntu’.

Google has confirmed it is working on a desktop linux project called Goobuntu, but declined to supply further details, including what the project is for.

It’s possible that it’s just one of the toys Googleplex engineers play with on Fridays, when they get time off from buffing the search engine code or filtering out entries about Tiananmen Square.

It could be for wider deployments on the company’s own desktops, as an alternative to Microsoft, but still for internal use only.

But it’s possible Google plans to distribute it to the general public, as a free alternative to Windows.

Google has already demonstrated an interest in building a presence on the desktop. At CES Las Vegas this month, it announced the Google Pack, a collection of desktop software bundled together for easy downloading.

The pack includes many apps which compete directly with the Windows bundle, such as Google Talk, Google Desktop, Mozilla Firefox, the Trillian instant messenger client, RealPlayer, and Picasa photo management.
