I’m still in my 20s, but as of a few years ago I started forgetting what’s my exact age. I always have to stop and recalculate it each time someone asks me. I get asked fairly infrequently, but when I do it’s a bit weird/embarrassing that I have to say “wait, let me calculate”. (I know when I was born, of course.)
It seems as if there’s no good reason I’d remember it, since it changes all the time and it is rarely mentioned in practice. But others, including people much older than myself, know their own age immediately.
I’m also terrible at remembering people’s names, I don’t know if that could be related?
I went from saying 20 something to saying 30 something and I’ll brobably keep it up each decade but after 50 I’ll just say old. Actually I already say old more often then not.
It’s more important how you feel. so if you can keep up with the 30-somethings in your 50-somethings, might as well not rub it in, right?
