They were super into singing-- I was attending college to get a music therapy degree (I switched to music composition eventually). I was always more into music theory than I was into performance-- it's the math of music.

As a kid I was into Star Wars and got involved in online gaming in the 90s, before there were traditional online multiplayer games... had to do P2P connections. I read a lot of Star Wars.

As a kid I built my own PCs...

I became a meat cutter... Went down an artisanal bread rabbit hole...

I'm a foodie and I work as a specialty food broker (spent some years working for a specialty food distributor)

I'm on the Discord Hype Squad and I work with companies to build Discord servers (some as workspaces, some as community hubs).

I used to stream mobile games on my Youtube channel, specializing in theorycrafting explanations (if you're bored: https://www.youtube.com/watch?v=HBiVyhKnpqs )

I got very into Classic World of Darkness TTRPG and started the first CWoD community server....

I'm sure there's more but there's a limit to how much random stuff I feel like listing before it becomes ridiculous (and I am certainly an expert in ridiculousness)
