Says I could take on 28. I figure if it was a swarm of kids hellbent on attacking me like a pack of zombies I'd not feel very bad about fighting them. It does seem low though because a 5 year old isn't exactly going to have that great of endurance against a full grown adult. Unless it actually was a zombie child then it might actually be able to take more than one hit and keep coming.

I can take 29 90 year olds apparently. Only one more than if I was battling a horde of 5 year olds. Really though old people would seem to be a lot less dangerous than a group of five year olds because a 90 year old generally isn't going to be anywhere near as fast as a small child. Plus the exertion of fighting might thin the group with heart attacks, saving you some effort. I'd certainly feel less bad about beating up an old person too, because they are old enough to understand the consequences of attacking someone.
