Former absolute world boxing champion in the heavyweight category American Mike Tyson said that as a child he put up several fights every day.
I must’ve had three or four [street] fights a day. From like age nine… I was 200lbs at age 12. I was fighting the kid, then fighting their fathers. They were crying, went home, and got their father. Then I would fight the father.
