What are you engineers, physicists, and scientists planning to do when you retire? If you are in retirement now what are you doing? I am mostly interested in hearing from those who will remain active in their chosen profession. I am looking at retiring from a computer engineering career in maybe 5 years time, and I was thinking of some things I could be doing to keep myself busy and have fun: 1) Volunteering, in particular teaching or tutoring public school students in STEM. 2) Going back to graduate school for a third degree. Why? Because I enjoy learning. 3) Getting back into tinkering with computers on my own, becoming a "maker" or amateur inventor. 4) Starting my own business. 5) Working part-time or contract when I feel like it.
