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 watch episodes of Star Trek before going to sleep often just falling asleep to them. The nice thing about Star Trek is it ranges from good to bad so you get a bit of everything. Also I’m not 50 so your results might vary.
