I'm feeling that I should admit to having a single daily cup of coffee, usually in mid-afternoon.
Some of you may remember that, on the advice from my MD because of stomach problems, I was trying various ways to reduce caffeine for several years.
I'm not sure what it might have to do with memory and daily routines like the mother there with the dog and little kid

. Memory has
captured some interest in my senior years. Yesterday, I was watching a tiny kid about that toddler's size in a parking lot. The dad was
several steps ahead of him but I guess Dad thought it was safe because they were passing through disabled parking access. The little guy gave a
bounce when he came in sight of their vehicle.
Kids holding parents' hands often (usually) are skipping their way through parking lots. The little toddler was too young to be a Skippy, certainly not without holding a hand. I see lots of kindergarten kids on the school grounds on school days. Walking? Nah, everywhere, it's at a run. Most of this is enthusiasm but I have to believe that the bounces and skips, and the running, has a lot to do with learning and reinforcing the memory of how to move like that

. Muscle memory, I guess that it is called. Works for habits of all sorts.
