I'm in good shape still, nothing hurts, but my goodness since I was about 40 everything takes forever to heal. Injuries that might have healed in 2 months when I was a kid can take 2 years to fully resolve. Why, when I have fewer years left?
I don't get the music thing, I think maybe men are more nostalgic about music. I listen to a broad sweeping set of artists old and new, and my kids do too (one is a musician but all of them will hear something on tiktok and go find it). I still go see new and emerging acts, love finding new music.
Oh! And since nobody is talking about the positive things that happen when you get old: around 50 my green thumb arrived, I no longer kill plants by looking at them. I can coax them to grow. And can cook just about anything too, but that is accumulated years of experience, the plant thing just came like a gift. Around 45 I got the power of trust, like anyone would tell me anything - middle aged white lady power, people tell me things, I could be a spy or drug mule or something now and just skate through security, I am not suspicious. And mood gets easier to manage too, not so quick to anger or fear.
On the trust thing - every once in a while I'll go to a concert by myself, stand in the back, and enjoy the moment and remember the old times.
More often than not, three or four young ladies will come up over the course of the evening and start giving me their life stories and their relationship struggles and whatnot.
This isn't a flirting or drunk thing on either end of the equation. In that moment, they just seem to need somebody to listen to them.
