and i'm not sure i've ever heard of a drug that improves coordination... which is what being able to skateboard is 95% based off of. in fact, whenever i've put on muscle in the past, it's thrown off my skateboarding.
all in all, DAO is full of shit as usual and you shouldn't even bother with that bored moron.
i'm nearly positive dude is on some clown-trick skateboarding. most talented people are humble about it, skateboarders in particular.
