Pretty much all of them at this point, I'm in the construction industry. Video games, reading, computer repair, anime, dungeons and dragons, miniature painting, watch making, chess... There are a few brave exceptions, but most people give me that glazed over look when I bring it up.
I just posted a similar response but I think the issue, at least for me, is how deep into the weeds I get with each subject.
Anyone can be into coffee for example, but it's the ones who do the research and watch the videos about the subject in their free time, that make a simple thing such as coffee become more of an obscure thing. 🤷‍♂️
The example I like to give for coffee is that I watched James Hoffman sift coffee grounds to eventually brew a cup with all the same size grounds. With no intention of ever doing that myself.
I went searching, but all I could find is his review of the sieve, which I've never watched. But, I know 100% that it was him and this sieve just in a different video....
Chess is such a great game, it has it all. History, drama, things to learn, things to figure out, attacks! and defences, in an everlasting suite of games...
Fun fact ; when you exit the opening sequence (3-4 moves for beginners, 20+ for grandmasters) the game quickly becomes a game never ever played in the entire history.
