What man VOWED to return after voluntary death to tell the world what's on the other side? 18th, 19th century maybe earlier.
I once read about a man sometime in history who voluntarily let doctors put him to death in order to see what's on the other side - life after. He vowed to return and reveal it to the world, but no one's heard from him since. I can't remember where i read it or who it was but it's a true story. Maybe in the 18th or 19th century, maybe earlier. Thought is was pretty funny though. :-)
