Re: What's your other passion(s)?
Science! I'm a major science geek, and I will watch just about any science-related documentary I come across. I have a special fondness for astronomy, but I'll read and watch just about anything. Geology, astronomy, history, biology... Can't get enough :-)
Since I don't work in any scientific field, I don't have much practical application for the knowledge and facts I accumulate, expect that people generally don't like playing against me in Trivial Pursuit :-)
