Avoiding carpal tunnel / repetitive stress injuries
gtani: see keyboard review threads:http://news.ycombinator.com/item?id=185743http://developerlife.com/reviews/?p=46http://news.ycombinator.com/item?id=221434http://news.ycombinator.com/item?id=199493http://news.ycombinator.com/item?id=104977That's about 3 days' reading material: some bullets as i dimly remember:1. laptop keyboards: avoid, especially for emacs/textmate control/alt/command key combo's.  These 2-key to 4-key combo's are hell on your wrists if you always have to do them on the left side. If you do COntrol_C and X and V to cut/past in windows, same deal. I think it helps to use both short-travel scissors mechanism keyboards, like the new aluminum mac KB's and older-style long-travel sprung keyboards taht logitech , Matias and kensington make.  I especially like the Matias' feel.2. hourly breaks and wrist exercises: wrist curls, reverse wrist curls, the Dyno-flex ball , powerWeb exercises.  The latter is expanding your semi-closed fingers out against resistance, which is one that I rarely read about, but it's important.http://www.fitter1.com/Catalog/Category/35/HandWrist.aspx

Try to mouse with undominant hand (I'm not too good at this)4. consider other factors: cocking your wrists when you drive or ride a bike or work power tools, shovel snow, brush your teeth, sleeping on your side.  The combination of weight-bearing, pressure/shock/vibration and closing off the outside or inside of wrist joint is insidious .5. Aside: i think JFred has enough material for a book.  all my upmod points to him/her!
