why do you faint when somebody punch you very hard???

Answer 1

There is actually very little known about what exactly causes a knockout but many agree it has to do with minor trauma to the brain stem. This usually happens when the head rotates sharply, often caused by a strike. A common misconception is that a knockout is caused by compression put on the carotid arteries in the neck restricting blood flow, but this is in fact how a choke out works. A basic principle of boxing is to defend against this vulnerability by keeping both hands raised about the face.

Answer 2

I'd hardly call it a faint. It's just how the brain reacts to trauma, too much trauma and it just shuts down.

Answer 3

If someone sucker punches you, it can happen because your not expecting it, which gives you every right to sucker punch them back. If you see it coming, grit your teeth together tight and get mean; bones and bruises heal, pride usually doesn't.

Answer 4

The brain bounces around in the skull, causing a blackout.

Answer 5

Because our brain bumps into the skull and it cause K.O!hehehehe.

Answer 6

I'm pretty sure that's called a 'knock out'.
