One of my fears is quickly losing cognition after retiring. I'm a WFH developer so I'm hoping that lets me extend my working years a bit longer than others can, but I need something to occupy my mind 30 hours a week after that. The idea of just ending up in The Villages driving around golf carts for the rest of my days seems very ominous. My hope is to find a problem space to research in, there's a lot of capacity in unsolved problems to improve a lot of lives around the world. People die every day from diseases that we've solved in the west 50+ years ago, and there's a lot of work that can be done to make sure humanity has access to existing solutions for example.
