I'm into math and coding. I guess that doesn't really count as a hobby since is also my job.
I like occasionally learning some new magic trick. Right now I'm trying to learn the coin roll. I swear if I'm ever reborn I'm definitely gonna be a magician.
I guess this also relates to the coding one, but I also like typing and I enjoy playing typing games online, or just typing random stuff for the sake of typing. This whole post is an example of it.
I used to be into martial arts, but it got scary after getting hit on the face seriously for the first time, and I decided it was not worth the risk of getting permanent brain damage.
Biking used to be one of my favorite hobbies as a kid and teenager, but ever since my grandma decided to gift my bike to one of my cousins without my permission, I haven't been able to do it again. I once visited a city where the had bikes all over the place and you could travel like that, the street were designed for it having a special bike lane and everything. I guess it was fun while it lasted.
I wonder, what made you change your mind about it?
