yo, i reccon im prettey healthy, i dont do drugs, i dont smoke and i dont drink much alcohol. 
 
i reccon i dont get enough sleep and i dont drink water quite enough. 
 
also, through riding (i think), i had big problems with my back and now my knees are starting to give in  :P  :huh: maybe they are just bedding in to me doing a few different style moves and changing my style a bit? i dunno :P 
 
anyways, id say im prettey healthy apart from the knees, lack of sleep and de-hydration, lol :P 
 
cheers
