Ok here’s a tiny thing:
I was reading something about Martin Gardner recently, who I’m sure you’re familiar with, in which they said that he of course loved puzzles of all sorts and gave a couple of examples.
The one that stuck in my mind is this: why does a mirror reflect things left-for-right and yet not top-for-bottom? I confess I don’t know the answer but have enjoyed puzzling over it (and I have a good excuse for having a scrambled brain just now 😉 ) and I hope it brings you some pleasure also.
Best wishes to you and yours,
