Racing: I autocross with the Sports Car Club of America. Basically, it's driving around a course laid out in pylons for fastest time. Also, go karts :)
Astronomy: Here's a couple fun facts. 1) We're all literally made of stardust, as many of the heavier elements in our bodies was created by supernovae. 2) Given enough time, hydrogen will start to think about its own existence.
Food: Food is good. Good food is amazing. Amazing food cannot be described in words. Sushi is one of my favorites. Also, go watch "Jiro Dreams of Sushi", seriously.
Space Travel: One of my goals in life is to help increase access to space. I've taken apart, assembled, fueled (liquid oxygen is cold!) and helped test liquid fueled rockets. Making supersonic hot flamey stuff come out the bottom is pretty damn neat.
Technical Theater: Mostly lighting design and electrical work, but I've been known to act once in a blue moon or two.
That's a good start for now. The rest, we'll save for later!
