Re: throat

<<<Why do people die if they have their throat cut ? I thought if it happened,
you could put your hand or something over the cut to help you breathe.>>>

An effective throat-cutting also severs the carotid arteries. Your brain would
blink out before you had a chance to cover them, and in any case you wouldn't
be able to restore flow, so you'd be dead anyway. 

Hope that helps with your science report <G>.
