There was always that one arguement that folks (parents usually) have against video games. "Video games makes you fat and lazy from sitting around all day and eating junk food. Go outside and play!!!" My parents always gave me this lip service when I was young. Thankfully I don't have this problem with the little guy, as you can see from the video below.
This is the way he plays games, always. He'll go into his room, play for a while, then an hour later, he'll come out, dripping in sweat as if he ran a marathon. Being that he's currently growing up on the Wii, the motion controls kind of got him that way, even when he's playing Super Smash Bros. Melee with a Gamecube controller. Sometimes when he's watching me play and I'm in an agressive situation, he'll start jumping around like that as well. The guy is going to have some strong legs.
