If you have ever been in a near-death experience, you may have seen your life "flash" before your eyes. I've asked several people about this. They said that it was like they went through their whole life in a second. That's not too far fetched. Your brain likes to avoid stress, so that it does not have to deal with facing death. So if your brain was to think you were going to die, it would go to the easiest way to escape: memory. So when it comes close to the end, your brain turns on every memory you ever had.
The brain will also stay alive for about 7 minutes after you die, provided your brain is intact. So if you have 7 minutes and you can experience your whole life in one second, that's 60 lives per minute. 420 lives in 7 minutes. That's a lot of time and a lot of experiences with death.
How much time do you have left?
