not washed up at all, that dude just does everything that might excite him. Hes only what like 29? he's got a long time before he starts going downhill, for all we know he hasnt yet reached his peak of his ability. Though he has fucked his body, i dont know if its effecting him, he just keeps getting crazier and crazier. but at some point all that abuse will take its toll and he will have to take it easy.
Nascar will be interesting, i dont think his talent is on 4 wheels personally.
