Anecdata: my father died relatively young in his 50s after a decade of ill health that had forced him to give up some of the things that he loved, like sailing. This made a very big impression on me (I was in my mid-20s), specifically that you only get one life and you must make the most of your health while you have it. I am now older than he was when he died and I don't have a bucket list of things that I want to do in the future. That's because I've already done those things, rather than postpone them until I retire. That said, I'm currently in the process of seeing if I can bootstrap a totally new career for myself, in the outdoor conservation space after decades in the office in the s/w industry. I might not make it but at least I've tried.
YMMV.
