I agree with you. Actually, Lemmy woke me up to how much reddit had already been enshitified. I didn't realize that I had stopped commenting altogether because the subs were so big that either no one saw your stuff, or there was always some one pissed off who felt the need to respond. Lemmy reminds me of reddit the way it was when I joined 12 years ago.
I think it's that you don't feel older mentally. I though I would feel a certain maturity once I reached an age where I had a solid, advancing career and owned a house. Turns out, I feel pretty much the same and am just better at dealing with things that arise and pretending that I'm mature. My body hurts more and my face looks older, but I don't feel all that different. I'm sure I've mentally changed to some extent, and I notice it more when I talk to younger people, but I still feel the same.
