Retirement is a function of money/wealth, not age.
If you’re immortal, you’d (not you specifically, just whoever in general) have to be a complete tool to go through hundreds/thousands of years without generating at least enough wealth to retire at some point.
So, when I was in highschool (circa 1996-ish) I couldn’t sleep one night. Decided to walk down to the 7-11. There were a few pinball games in there that I played before, but never really took it seriously. Popped in the quarter and got my ass handed to me. Decided, fuck it, I have nothing better to do at midnight in North Dakota. Popped in another quarter. Ended up hitting the multiplier in the top left corner. This machine was so worn out that I kept pushing the pinball into the multiplier slot. It got stuck and just bounced around there for a while. I eventually lost the ball, but now I knew the secret. Put the ball in the upper left corner. Every game after that I would aim for the upper left corner and it would just stick up there earning points. I eventually got bored at like 2 am and left the machine with like 65 free games from all the points I gathered. Fun as hell.
