It's a matter of brain chemistry. Back a few years now, bought my
mother a VCR. Spent a number of days over a month's time trying to
teach her how to use the onscreen programming. Nada! It ended up
sitting there completely unused.

Haven't we all seen the 12:00 flashers in our time? lol

Then I bought her a microwave with three levels of programming. Came
back two days later to show her how to use it and found she'd already
memorized its entire operation.

Maybe it's a cooking thing as my mother does the same. Loves to cook
but can't operate a tv/vcr/dvr remote to save her life.

Brain chemistry I tell you!

You may very well be right.
