Drinking, smoking, pot. Both my parents are super heavy into all that stuff (drinking is more my dad's thing then it is my mom's - she's usually the DD - but she'll drink occasionally) and I told myself from a young age I wouldn't do any of that because it wasn't appealing at the time.
Turns out alcohol and pot are two things that decrease the spasticity in my lower body to the point where I can actually walk better even if my balance is still shit. Imagine my surprise
Sex. It scared me for the longest time in no small part due to mobility issues. Funnily enough it turns out that I have a pretty high libido. Never would have guessed.
The Fast and The Furious movies. I really like fast cars apparently
