No they don't, it's a ticking time bomb to be that heavy at "5'10"
Say that to a fella I know, 5'7 300lb, FAT. Has been like that for the last... 15years, 55 currently, drinks till a skin gets yellow, to hospital, a few days there, they bring him "back to life", a month sober, then rinse repeat - 10-15days driking, hospital... I'm sure he will die soon, but still.. it's a body of steel. And doctors are in fukkin awe, becuase his organs somehow manage to "spring back" from a point where they thought there's no way out many times already. Go figure...
