Just to throw it out there, I'm a huge nerd. I like to immerse myself in anything that has a history, universe, subculture, whatever. I find so many things fascinating. After giving it more thought, I think the reason why I enjoy being a nerd is because I enjoy being being passionate about something. I don't think a "nerd" is someone who likes a certain category of items but rather somebody who cares deeply about a particular interest. And I believe it is a sense of passion that makes this world an interesting place to live in.
Seriously, I did not mean to get on a soapbox there nor mention the word nerd as much as I did, but c'est la vie.
While I'm a huge nerd, I do enjoy being fairly active. I enjoy working out, and am totally obsessed with baseball, with the Atlanta Braves being my favorite team. I absolutely abhor football, but I can understand its appeal to others.
