13. Thaw your brain!Link (via Boing Boing). This reminds me of cool experiments we did in science class in middle school (incidentally, had I already informed you of the magnitude of my nerdiness?) like this one:
Too much Chipwich too fast will freeze the brains of lesser men. As for you, press your tongue flat against the roof of your mouth, covering as much as you can. "Since the nerves in the roof of your mouth get extremely cold, your body thinks your brain is freezing, too," says Abo. "In compensating, it overheats, causing an ice-cream headache." The more pressure you apply to the roof of your mouth, the faster your headache will subside.
14. Prevent near-sightedness!
Poor distance vision is rarely caused by genetics, says Anne Barber, O.D., an optometrist in Tacoma, Washington. "It's usually caused by near-point stress." In other words, staring at your computer screen for too long. So flex your way to 20/20 vision. Every few hours during the day, close your eyes, tense your body, take a deep breath, and, after a few seconds, release your breath and muscles at the same time. Tightening and releasing muscles such as the biceps and glutes can trick involuntary muscles -- like the eyes -- into relaxing as well.
Find a place (a hallway, perhaps) where the walls are the right distance apart and stand between them, arms outstretched to each side at shoulder level, with one palm flat on each wall. Push against the walls firmly for sixty seconds. When the time is up, step away from the walls with your arms still at shoulder level. Despite your best efforts, your arms will slowly descend to your sides. Ooo eee ooo.
