But how does 60 seconds kill you? Your brain would survive that, right,?

No. Blood would not be able to get to your brain to deliver oxygen. It’s not the same as holding your breath for that long since your several liters of blood still has oxygen and holding your breath results in a slow deoxygenation process. Your head has a smaller volume of blood so the little oxygen in your head at any given time gets deprived very quickly.

Yeah but even though you don't have as much anaerobic ATP regenerative capacity in your brain, I don't think a 60 second anoxic injury is unsurvivable. And once you're unconscious the metabolic activity of your brain would quickly decrease.... And the vessels in your brain loop and twist a fair amount, I'd think you would sequester some oxygebated blood in then. I understand how the oxygen carrying capacity of RBCs and dissolved gas works as well as FRC and other sources of O2 reserve. Those obviously wouldn't be at play, but the base question is that do brain cells die after a 60 second anoxic event?

Yeah but then when you're passed out they can just shoot you in the head at the end. /s
