Gaming. I’m in my 30s and the 30s was the age bracket I’ve heard where few can carry on gaming through, because it has a tendency to die here. I piss away so much time doing other things that gaming just takes a backseat. I’m not even married or have kids.
I assumed most things would get more difficult as I age. Turns out I was correct.
The only thing that is easier is building something from a box of scraps. It’s harder to see and my hands aren’t quite as nimble but I have a boat-load of experience.
Tinkering with electronics, it was easy when we had through-holes and young eyes, now with SMD and presbyopia it is pretty hard.
So much learned over a lifetime!! I love the giant bucket of weird knowledge and skills that I’ve accumulated in 50+ years!
