When I was in my 30's I met a lovely lady in her 80.s walking, and we became great friends, going on walks together and getting up to various things, as we had similar attitudes. Hated boring shopping for clothes, walking round shopping malls etc but would go off to walk along the coast or by a river etc.
One day I suggested we went somewhere and she replied that she was sorry but she was "driving some of the old people to the shops" We would go off for walks, and she happily climbed stiles and wandered along, with her saying Use it or Lose it, but remind me not to tell her daughter what she was up to. Well in my eighties now I try and keep up her good ways!
I used to teach TEFL and of course there were many lovely mistakes made by the students, and you could tell those who were improving and who were the advanced ones, especially when they understood a joke, that was not a visual one.
