What disorders and diseases commonly afflict programmers?

The only one I can think of is the Carpal Tunnel Syndrome, but up to now, I still don't know anybody who has suffered from it.

Please only post those disorders and diseases that you or some other programmer you personally know have acquired from programming.

Edit: I was just recently diagnosed with GERD, which was caused by my excessive amount coffee, which stimulate gastric acid secretion that causes the thinning of the esophagus. Just imagine yourself without an esophagus just because you drank too much coffee. That's for drinking an average of 3 mugs of coffee a day on weekdays. On weekends, one liter a day.
