This is interesting. I'm about 6'3 and weigh about 100kg and pretty fit so i'm a fair size and i have always had people tell me they wish they were as big as me so no guy would ever pick a fight with them. But i have noticed being big doesn't keep you out of trouble - it gets you into trouble. There's always some guy who wants to test you and maybe show off in front of his mates so they go after the big guy first.
I agree with you, back in high school when I went out with my mates, the 6'2- built-like-a-brick-****house guy in our group was always the one that drunks would pick a fight with, the rest of us were small in comparison but it was always him that the heroes would go for first :confused:
