This Book Is So Goo...What's For Dinner?

If I were to arrange books in a book store, my system would not be too far from what the cartoon on page 375 displays. I found the cartoon particularly comical because when I read my mind wanders like crazy. In the cartoon there are three sections on a book shelf titled "Attention Span" the three sections are short, medium, and long. In the first section I would have like easy leisurely reads nothing too serious. In the medium column I would put like novels and books that have a series, reading that is a little more advanced. Lastly in the long section I would have all the boring stuff like documentaries, books on law, and books of that nature.
