If you could experience being dead for one day to learn what happens in the afterlife, and were guaranteed to return to life the following day, would you do it? Why or why not?
No, that's how you get zombies. Even if someone doesn't find my body and start autopsying or embalming, it'd still go through rigor mortis and decay. My clothes would require laundering, and I'd really have to take a shower. After a day of no oxygen, my brain would be useless. (Shut up, Imaginary Heckler.)
I'll eventually find out anyway. I can wait.
