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 never expected to have lower back pain in my late 30s. And it was pretty quick too. Within 3 years, I went from playing casual basketball a couple of times a week to not playing at all.
