Those overweight and unhappy about it probably wouldn't admit it. What would they gain from it? And, I'll assume (though, last time I did, I was quickly lectured for it), most of the overweight players would spend their time playing the game, not hanging out in the Off-Topic section of these forums (it's been said many times, the majority of OT regulars are retired or semi-retired). It'd be stupid to say that all gamers are overweight. But it isn't completely idiotic to reason that many, if not the majority, are.
