BTW, if you're wondering, you can't die from holding your breath. If you pass out, you will automatically start breathing again. So feel free to try this experiment
[note: if you pass out and land on, say, a plastic bag, this rule will have no jurisdiciton on the fact that you will suffocate. If you try this, aim your body so it will not land on a plastic bag or other suffocating devices. Thank you]
