You The Owner's Manual by Michael F. Roizen, Mehment C. Oz

I enjoyed this book much more than I anticipated. I read it as part of my preparations for a test I took to bypass some elective credits at school. (It worked; I passed!) There is a lot of information in this book that I should have known but didn't. The subject matter is presented in a way that keeps it interesting all the way through despite my fears that it would be a snore-fest. I'm glad I finally had a compelling reason to work through this and now I'm even happier that I have a copy on hand for reference.
