Here’s a fun memory.
This was in the early days of freedom, when we were still kinda in shock, and very much enjoying how lovely it was to have a normal life.
We had some rules right away for saving money. One is “that engine doesn’t start for anything less than two miles”, so we walked to most errands. There were playgrounds nearby that we passed.
I watched the kids playing on the monkey bars, and remembered that I had loved to do that, long ago. Who says I can’t try? By age 45 my hands were pretty out of it.
It wasn’t even so much a grip strength thing as that the soft skin on my hands just couldn’t bear it. I gave a try, and had to stop within moments. I went home with hurting palms. A few days later they were okay again, and I tried again.
A dozen times of that and I had callus again like I did when I was young.
