for a while now I've caught myself standing while playing video games, ever since guitar hero, I've started standing up and playing when i start getting frustrated, but then i don't sit back down, and end up standing in front of a tv for hours trying to beat a game. so far I've lost 35 pounds and have kept it off for months. it kinda nice but now my legs are always sore and stiff, does anybody else do this or an I just a freak?
