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.
Fitness. All my life I’ve been athletic, running competitively when younger, which eventually switched to doing years of gym & becoming very muscular. Unfortunately injury eventually curtailed that so I switched back to running in later years for exercise & enjoyment. I tore the meniscus & the surgeon found other issues.
TLDR I’ve always been a fitness fanatic. My body gave up before I was ready to give up
