In my opinion, it's good preventative care.

The problem with tendinitis, carpal tunnel, bulged neck discs, and health issues that afflict programmers is that you don't know you're susceptible until you already have the problem. Then you're looking at months or years to fix it and learn techniques and equipment to avoid its return.

I suppose it's always possible, but I've been spending approximately a third of my time in a chair at a computer since I was 12 (I'm 27 now). Essentially everyone I know who does the same has had issues, but I never have.

Yeah, and I never had a moment's back or neck pain, despite terrible posture habits, until a bulged disc put me out of work for a long time at the ripe old age of 34. I genuinely hope you never experience any work-related ailments.
