Is it the bullet to the brain that kills ya or the little fragments of fractured skull grenading into it? The world may never know.

I don’t think I want to be Alive after a bullet to the brains..

Depends on the calibre really.
If it's a .22 pistol and you do die, it's probably the fragments. If it's a .50 cal, it's definitely the bullet.

CSI could probably figure it out.
