Maybe it has something to do with his smallness; climbing in post lamps and stuff would've taken more energy if he was taller and heavier ... Plus he's probably got a lot of upper body strength compared to his weight, so it doesn't take as much energy from him as it does for most people. And of course he's done it for years, so his body is kinda used to it. Or maybe he's on drugs ... or he's half human, half monkey :dontknow:
