Well, Uni and my three girls keep me plenty busy, I end up sharing a lot of their interests, rocketry, board-games, a bit of photography, skating.
I also restore movies from 16mm/35mm or even from laserdisc if there has been no other release format.
We don't have a TV, and aren't on any social media (unless IIS counts) so you would think we would have plenty of hours, but they always seem to be filled.
I cook a lot too, but need to get more exercise so I can cook some more
