You can survive anything but death. And maybe even that.
Yup.
Been there, done that.
(A CPR instructor once insisted, despite my intense questioning, that once your heart stops - you're dead. Period. Might come back, but stopped heart = dead. A couple decades later, I had open-heart surgery. "Your husband is doing fine, they're stopping his heart now." Wife didn't like that. No idea how long that bit lasted, but it wasn't short, maybe 1-2 hours. And I was, by aforementioned definition, dead. And now, thank God, I'm not.)
