It isn't hostility, I've dated a couple and my cousin is one. I just like to tease. And vegans do taste better. (If you don't get it, don't worry, you are too young to get hte joke.)

As for the ability to take 5, 6, 7 hits from something in the .4"+ class and keep coming, there are a number of cases. Drugs, booze, shock from another injury, and just being really, really mean and angry have all done it.

There was a guy in the early '90s who was sitting in a park threatening people with a shotgun and a couple of pistols, I don't remember where. When the cops showed up, he shot at them, so they called for tactical support. Long story short, a .308 Federal Match to the forehead, and he's in prison today, not the ground. His skull was thick enough to shed most of the injury, so not quantifiable brain damage.

Scared the snot out of the the guys in the morgue, I bet.
