Ive worked as a summer camp counselor with 5-11 year olds and Ive had many of battles against them. They can put a hurting on ya when they work together and attack from all fronts. Just a kick in the shin or knee causes some bad pain.
You have to use one hand to protect below the belt,so thats a disadvantage. And the training will show them how to wrap up legs quick and take you down to there height, where the real battle begins. A quick jumping roundhouse kick will drop the first 2 to reach me, then two hard punches will take another 2 down. By then you will probably have one on your back if you stay still. Its hard to sling the little punks off your back and it will slow you down.
With sufficient room to run I would have to go with 14. Im pretty athletic and could jump over them, and almost fly around the room kicking them in the head. But Im not strong enough to keep fighting once they get a hold of me and my endurance wears down. Over/under 13.5
Id bet over cuz of my speed.
who the hell thought of this?
EDIT: changing that to +/- 16.5 after reading a few others ideas.
you're overlooking some important things:
1) you get to wear a cup
2) i'm sure you weren't trying to take those kids out...put in the op's proposed scenario, you would fight much harder and be able to ignore more pain.
3) for all but the the weakest/smallest adults, your number is too low.
