George was a tremendous, heavy boned human...they don't even have to try. they just have so much more power than a normal human.
I have a friend...Mexican fella "big Dave" he stands 6'4" and weighs 375 solid pounds. Not "bodybuilder" solid...but he's a gigantic, sturdy guy who isn't a ball of blubber, almost as wide as he is tall.
well he hit me one day, just fucking around...flicked a jab into my ribs with nothing on it. Knocked me off balance and I though he broke my ribs.
