Know a network admin (who games all the time, spare hours) and a gaming junky, 30-70 hrs per week, both report bad elbows, wrists, thumbs, fingers, rsi of said bits. Stiffness, poor ongoing health, general fatigue, lethargy, low vitality, loss of interest in life, and being selfish lazy mofo's. Oh wait, I reported that last bit. Gee, any wonder why. If someone paid me to simply sit in a chair for that long, I'd have to tell them to get bent, even without screen radiation or feverish mouse clicking. Oddly, both have failed relationships, due entirely to excessive gaming. Online gaming....it's worse that heroin, people!!!
