Carperltunnel syndrome is basically repetitive motion syndrome.

DO ANYTHING over and over again in the exact same way will cause the problem. Ergonomics help blood flow, but it doesn't cure the root cause of the problem.

The root cause is sitting on your ass in front of a computer/desk for 8+ hours a day, then going home and sitting on your ass watching television for 6+ hours, then going to bed and sleeping on your ass for 8+ hours. Then repeating this for YEARS on end.

You're not moving your joints the way they were meant to be used (ie - full range of motion, not repetitive robot-like tasks)
