Oh. Yes, I notice some differences. At least, from photos, compared to now. And a few small skin things have appeared in that time.

And like I said, I have friends that didn't strike me as looking older than me that now I find do look older than me. Liver spots are a very visible one: some of my friends now have these. Creases around the eyes are another. I have some when I smile, others have creases in permanence. (And other friends the same age don't.)

Of course, it can be hard to separate aging vs. sun damage (that affects nothing deeper) vs. weight gain. All of those make a person look older.
