Yeah, not the smartest thing to do. "hey buddy, choke me until I pass out!" Yeah, that's one short cry away from murdering someone by choking them to death. You get light headed because your brain is deprived of oxygen. No oxygen=no life.

I actually heard of kids doing this in the paper while ago. Kids would hang themselves depriving themselves of oxygen, and their buddies are there to help them get down so they don't die. One kid dcided to do it all by himself and he hung himself by accident.

All just to feel a little light headed.
