Exercising is probably what helps you. Most RSI sufferers don't exercise enough (myself included). I don't think it has to do with habit; a lot of RSI sufferers, myself included, started using computers very young. Humans have evolved to walk long distances, but we haven't evolved to sit all day holding our arms in front of us in a relatively static position, doing repetitive wrist and hand movements. If on top of that you don't exercise, have weak muscles overall and bad blood flow... Well, that's asking for trouble.
