"What do gardeners and golfers do when they retire?"
They join AA. I've known several people who "realized" one day that the only reason they golfed was to drink, as there wasn't really much to golfing in the first place (something the rest of us already knew hahaha).
I hope to maximize a legal combination of work plus social security income, whatever is legal, as much as I can, and don't intend to stop working until I'm pretty old. Unless, and only unless, I can find really productive volunteer opportunities - in that case I'd like to be a full time volunteer for some program that helps people who are incarcerated and people who have recently become unincarcerated for reentry purposes.
Think about it - you're an ex con being released on probation. You aren't allowed to have ANY CONTACT with ALL THE PEOPLE you knew before - zero. You aren't allowed to drink or drug. And yet > You get dropped off in the middle of the night in the worst imaginable part of town, with no money, no charged phone, no ride, no home. And we scratch our head wondering about recidivism, they must just be awful people. No, our system funnels people into recidivism because of the incredibly obvious stuff I just mentioned, among others.
