Just read an article called 18 Tricks To Teach Your Body. It includes things like relieving tooth pain by putting an ice cube on your hand, or a way to beat blocked sinuses by wiggling a bone in your face. One of the tips sounded a bit weird to us though, so Laura and I tried it out and it totally failed. Basically, you hold your arm out and someone attempts to push down on it while you resist. If one of your feet is on a surface an inch higher than the other, you won't be able to resist the downwards pressure. Well, it failed, and we tried all sorts of heights! :) Any luck anyone?
