Geez. This thread is making me feel like I should be in pain 24/7.

I just turned 47. It was around 41 when I realized my body was changing, less testosterone, less muscle mass. The new routine in 2020 of working from home was a major physical hurdle for me to deal with. All sorts of pains I never had before. Stretching, walking, sleeping, hydrating, eating better all helped with weight gain and stiffness. Pretty much what everyone else is saying here. For me though, it was (slightly) more about the work life transition than the getting older part.

What I would add to the conversation is to appreciate your memories.

As we get older and the people around us start fading away, I've found I'm spending a lot of time gathering photos and videos and collecting things that have special memories associated with them. I've been frustrated recently that we (my friends and family) do the same things year over year or even week after week and all those memories start to blur together as we get older. The exception to this is if there's kids involved because you get to see them grow up so fast.

Make fresh memories. Embrace the ones you've made. Preferably all 'good' ones.

And I really want to promote the idea of printing photos, hanging them on your walls, and getting photobooks made. My uncle (who didn't have a partner or kids) recently passed and he had all these photos hidden on his phone. He also had a bunch of printed pictures from the '70s through the '90s that I'm in the process of scanning. We have this great technology to capture awesome images at any moment but they often get forgotten immediately after they're taken. Print your pics and have photobooks made that can be physically passed around and handed down. Sure, we can share digital stuff easily today but tech changes and people loose touch. As cool as image galleries are on our phones and how the AI curates them for us, there's still something very special about holding a few dozen printed photos to look through. Like, Spotify playlists are great for what they are but holding a few CDs or records in your hands is a great thing too.
