Hey, i have some questions about the twilight-vampiers, but im not shure if anyone has the answers...First: if a vampire wants to die, why cant's he/she just set himself/herself on fire....I mean, the material they are made of catch fire very easely, so why not? I have read somwere that the reason they are torn apart before being burne is only so they will be still and not try to put out the flames....

Question nr. 2: Is a vampires hair-cells just as hard as the rest?

i know it's just a fairytale, but if anyone knows, please help me =)
