That question is a weird one. Hobbies are hard to pin down, because what I love to do is make things that people find useful.
To that end, I've learned to crochet, leatherwork, some wood construction, I'm kinda learning to weld (slowly), I have basic programming knowledge, some automotive stuff. I can't even remember it all.
Interests: Psychology, philosophy, sociology, religion, etc.
I'm a jack of all trades master of none type.
