Your comment concerning imagination reminds me of a quote about the best way to experience a baseball game. First way was to be in attendance, second best way was to listen on radio, because with a colorful announcer the game could be embellished with various additions to what was actually happening, thus triggering the listener’s imagination. The last way was television.
Retirement helps. I worked until age 70, and now I have plenty of time. Best wishes for you.
