Great Invention Idea? Cure for Numb Thumb!


A Dangerous Habit?A Dangerous Habit?

If you're anything like me, you spend an inordinate amount of time typing away at your computer. You do so knowing every keystroke brings you one step closer to a carpal tunnel disease diagnosis; every glance at the screen teases your vision with astigmatism. So you buy an ergonomic keypad and mouse pad and you force yourself to look away from the screen every 20 minutes or so. Great! But now there is something else to worry about, something that threatens the great American pastime of television viewing: B.T.N.D. or Button Thumbing Numbness Disorder. Luckily, the cure is not worse than the disease. read more »
