Personally, I've never really read fiction. When I was in 1st grade I got mad because all the teacher read were stupid stories and I wasn't learning anything. My choice in reading material at the time was anything about dinosaurs and Ranger Rick magazines. I think I was also the only person that ever checked out the old Time-Life (I think that's what they were) science series of books that the local library had, so they just gave them to us. Even to this day that still tends to apply. The last whole book I can remember reading that wasn't for a class was a philosophy book - "Metaphysics" by Peter Van Inwagen. It was a good book, but probably requires some philosophy background to readily follow.

Usually if I want some sort of non-fiction type entertainment I see a movie or turn on the T.V.
