Exhale and count to 60, and your brain keeps running off the oxygen still in your bloodstream. Evacuate your brain of blood, and it can't do that; as deaths go,

Exhale and count to 60, and your brain keeps running off the oxygen still in your bloodstream. Evacuate your brain of blood, and it can't do that; as deaths go, this one would probably be faster than a neck tourniquet, but slower than the .50 BMG to the head I mentioned elsewhere in this thread. (How can St. Peter tell who died that way? They're the ones who ask him "What the hell was that?")
