Yeah, but also this would cause problems because if lets say some magic being goes up to you and says you will die on the 20th of April 2045 (random date) you will live to the fullest till then, but with the knowledge you'd go and do stupid stuff knowing you can't die until that date, so it will just be stupid. And confusing.
But I'm all for it, means I won't need to worry about working towards a place in life and just living it, doing what I can before I go etc, death doesn't scare me so bring it
