Oh boy, there are many: Politics, cooking, Flight Sim, fishing w homies, swimming, running, gym, tutoring my students (Latin, Biology, Physics, Chemistry, Maths. Everything is high school level, age 18/19). Next summer I'll start Medical School as well; so that's definitely going to be an awesome, intriguing "hobby" :D, and I can't wait to start that new adventure, yaayy!
Edit: I always enjoy watching netflix with my 17 yo sister :p
