well, if its any consolation, i've aggravated my RSI through over doing it on FM. It's a pain in the backside, and absolutely screws up my whole arm.
(And can also cause problems with self loving sometimes so need help from the other half)
Yeah I have back problems because of my computer usage. Usually I use it lying on my side in bed or with it in my lap, hunched over. Both have seem to taken a big toll in my back the past year or so, which sucks because I'm only 24! Also my hands/forearms hurt real bad from too much FIFA, FM, or typing...my long posts really do a number on my fingers and forearms. I guess I'm a bit of a mess.
Oh and when your ear rings for a bit it's the sound of you losing the capacity to hear a frequency. Thanks to years of music my hearing will be awful, hopefully they'll have good healthcare in the future.
