Gonna be honest - once we have backups, I'm totally intending to go into seriously risky behaviors. So this is 100% the opposite of how I intend to live my life.
The Metamorphosis of Prime Intellect [1] describes a post-singularity world where an AI prevents people from dying permanently, and one woman in protest takes up finding creative ways to kill herself (and getting stopped and patched up each time) and turns it into a sport with a following... I'm sure there would be some people that'd take risks to that extreme.
