GEEKS OF THE WORLD, BEWARE: Sarah Pullman warns of poor computer posture, and the havoc it can wreak on muscles and joints:

What probably scared me the most was the description of the earliest warning signs of repetitive stress problems – because almost everyone I know experiences them. These include tightness and soreness in the upper back and shoulders, and unfortuantely people tend to carry on as usual until they have symptoms down into their wrists and elbows.

Most geeks I know describe pain around their shoulder blades and upper back. Almost everyone has this pain right where your arm joins to your back, kind of around the back of your armpit on your mouse arm. (You know the one. And you know what it's from.)

So what are we doing to ourselves!? Are we all going to end up crippled down the road?

She recommends yoga, which isn’t a bad solution. Take it from me — I’ve been fending off RSI since Reagan’s first term — it’s worth paying attention to this stuff.
