- gym, every day - reading (trying for 2 books a month in 2017, currently reading Surely You're Joking, Mr Feynman) - bouldering (indoor rock-climbing low enough to not need a harness) - guitar, try to get a few hours practice a week - piano (not very good, been playing on and off for 6 or 7 years) - drawing, only recently started doing this - programming, i try to not do too much of this since i do it for a living, but i like to do some small projects every now and then to stay on top of new things - reading theory of computation texts and practising math - i'm sure i'm not the only one here who's into F1 now, i have kind of fallen off watching hockey in the last few years and F1 has replaced it for me
Cycling, Motorcycling, Electronics design and repair, and various coding/hardware projects.
Then repairing cars is not really a hobby but I enjoy it. 8 hours in a 32ºF/0ºC wrenching on something makes me feel so much better than playing a game. Honestly, games are like the back burner hobby. Although, getting HD out of old consoles has led to a dangerous E-Bay purchase history.
