When I was 11 I actually got into a fight with 5 year olds... well actually I got into a fight with someone else, who seemed to have an army of 5 year olds at his disposal. Anyway, believe me, I know I was only 11 at the time, but it's not that easy, consider that they're all coming at you at the same time, they will just make it impossible for you to move in seconds, and once you're on the floor, you're finished (that's pretty much what happened to me.)
