Glad your health situation has improved. I went to an ENT recently for a sinus infection as told my lymph nodes were "swollen". Of course I was thinking worse case scenario. Went in for an ultrasound and fortunately it was negative.

You mentioned hobbies. Were you ever into gaming?

If I were retired, I think I'd get back into gaming. I've never been a hardcore gamer like so many techies I've worked with but I played in my youth and since then it's been an on and off thing but mostly off. Started play a few hours here and there over the past few months.

Ever think about taking a university class for "fun"? You might find people you can relate to that are on your level. And you don't have to suck up to any professors at this stage of the game. You could be the smart ass in the class that knows more than the professor. :)
