how to remain active? well mentally active..

I read a lot, both fiction and non-fiction (mostly history), write stuff on Wikipedia (mostly history again) and I repair old pocket watches.

that sounds like a good thing to be doing! 

Read, like Martin fiction and non fiction, mostly medieval and preRoman history. I do lots of puzzles daily, crosswords both concise and cryptic, word searches and alphapuzzles. Genelogical research, I've just had my DNA results back from Living DNA so I can find out more about my deep ancestry. Watch news and current affairs programs. Use AI to find stuff out, ask it random questions and see where it takes me and often surprise it with the links I make, I told it to stop flattering me and telling me how clever and unusual I am and it told me that the stuff I ask about and know put me at an upper educational and professional level, I still think it's flannel.
