Thanks for posting this. I've had a long standing tendency to get eyestrain headaches from the computer screen, and when I was writing my dissertation, my wrists hurt so bad that I couldn't finish my figures. Fortunately, an old draftsman helped me out using pen and ink.

Today, as a musician, I'm quite conscious of the health of my hands and wrists. When I hear musicians complain about wrist pain, I always tell them to evaluate their computer use.
