Muscles atrophy from lack of use - as an aging cyclist with increasing numbers of e-bikes all around, I think I may some day have to use one because of age, but what are all these younger people doing, cheating themselves out of exercise?

And so it is with many things. I wrote cursive right through the end of my high school years, but while I can type well on a computer, I have trouble even writing block lettering without mistakes now, and cursive is a lost cause.

Ubiquitous electronic calculators have eroded the heroic mental calculation skills of old. And now artificial "thinking machines" to do the thinking for you cause your brain to atrophy. Colour me surprised. The Whispering Earring story was mentioned here just recently but is totally topical.
