Miraculously enough I have no skeletal, muscular, or neurological problems - even though I've probably spent 20 years of my life behind a computer, for far too many hours a day - often with horrible ergonomics. But with that said, I don't think I want to bank on that lucky streak continuing forever...seen far too many people get debilitating stress/repetition injuries in their 50's, to the point that they pretty much have to retire.
