So nothing to do with changing diets?
But also yeah I don't deny button bashing can be an issue if you spam a game for hours upon hours for weeks on end, but do I need 6 hours of fucking advisory messages before I play my game? No thanks, don't care. Every now and again I read the advisory on the front page of a game to kill a few seconds on the bus, and it's just bollocks, sit in a well lit room blah distance from screen in an up right positiong - oh get bent I'll play laying in bed with a coffee precariously perched on the side board or a foot away from the screen on a desk at 5am in the morning whilst thinking "just one more turn" with the lights off. Play through the drowsiness and the pain ooo yeah.
Then again I've reached the point where if a modern game entertains me for more than five hours it's something special (total war series, the first fear game, civ, counter strike) LA Noire looks good but I don't have an x-box le sigh.
My fingers though are nowhere near as damaged as my knees are, and i don't use those to play games lol (and they've been bad since I was a teenager when I was still a highly active sort of person).
