Lots of stuff. History in general; DIY stuff, mainly with recycling; uncommon programming languages (the stuff that tends to get less than 5% usage on SO developer surveys, such as Nim, Zig, Elixir, LISP, Vlang, FORTH); 3d modelling; astronomy; understanding different cultures (which is kinda an offshoot from history, I guess); drawing; games (video and board); writing fiction
