Crazy kids

Imagine you are standing in the middle of a field. Surrounding you are an infinite number of children that are trying to attack you. Their goal is to kill you, and they have three hours to do it. Obviously, if these were 6 mo old infants you’d be able to fend them off the 3 hours and survive, but if they’re an infinite number of 10 year olds, they’re taking you down. My question is at what age would you not be able to fend them off the the three hours, resulting in your death? [3336C]

This sounds like a word problem that requires differential equations. AP’s math is rusty. Kids have a pretty short attention span, so I could outlast a group of 5 year olds who’d get bored in a few minutes. I’d have to worry about falling asleep; then even those just old enough to crawl can then tie me up, like Gulliver, and try to do me in (although I think Gulliver got loose easily enough).
