Masturbating to rare porn.
Masturbating in general.
Play an instrument. Honestly God tier if you get dedicated. Maybe anytbing music related. There's all sorts of brain gains, and even social gains if you like. It's obviously better to start young, but it's never too late to try.
Lifting is an obviously one. You get stronk, hopefully learn a bit about nutrition, look and feel better, and there's still brain gains.
There's all sorts of other shit you can try. Auto mechanics, racing, programming, robotics, astronomy, martial arts, visual arts, masturbating, fucking brewing coffee if you feel that's worth your fucking time. Have fun OP

Paintball. I just started a couple months ago and goddamn is it fun. It's also a workout too, which is nice.
