Technically, you can't judge a book by its cover unless its cover has stuff from the book...I think. In any event, this book does have a little Myelin Sheath man, but he doesn't have a blind mouse coming out his butt. (Damn, now I want to go back and add that into the book somewhere...even if it makes absolutely no sense. The chapter title would be: Turtling a Blind Mouse.) As for the rest of the stuff on the cover, it will be clearer in the book...regardless of how clear the sentences may or may be. Therefore, read, don't read, flip through, or wipe your ass with this book. I've got two other science books that are currently turtling.
