I feel sorry for him though, if he carrys on growing untill hes an adult, he will have medial problems, like having to be in a wheel chair from his weight + height, because his bones cant support hs weight.
Guys just because hes big as all hell doesn't mean he's going to be great at all these sports automatically because of his size. But yeah like Kazama said I feel a bit sorry for him, if he gets bigger by the time he's older he'll have some major health problems.
he is 13 now... but in like 4 years he is gonna be well he could be majorly screwed up with health issues as moch said above.... but for 13 that is big and i as well feel sorry for him...
