Two things that computer geeks do a lot of are sitting and typing. Unfortunately, as I know from personal experience, that can lead to both back trouble and wrist trouble. The best books I've found on these topics are The Back Pain Help Book and End Your Carpal Tunnel Pain Without Surgery. They're probably available at a public library near you, so if you sit a lot and type a lot, do yourself a favor and check 'em out.
