Why Do I Drool?

We all poo and grow, and most of us will have, at some time or another, sneezed, bled, drooled or had an itch. These are all ordinary life events that we may just take for granted, never really questioning “why?” we do them or why they happen. Children who read the six books in the “Why Do I?” series, however, will come away with new understandings, especially in terms of how the focal subject matter of each book contributes to a person’s health. As has come to be expected from books in Crabtree series, this title has an opening table of contents and a closing page containing a brief glossary of words highlighted in the text and an index. All books in this series are illustrated with cartoon-like art.

“Drool” is the somewhat gross hook in the book’s title, but Why Do I Drool? is really about saliva and, in particular, the role it plays in digestion. Like the other books in this series, this one has a double page spread that requires the reader to turn the book ninety degrees in order to view it. The “Chew and Swallow” spread illustrates an open mouth containing a hamburger. Brundle provides four labelled steps of the chewing/swallowing process, with three of them involving saliva in a significant way. The book’s text also touches upon the role and care of a person’s tongue and teeth. Two pages of “Drool Trivia” conclude the text portion. Did you know that “[e]ach year, you produce enough saliva to fill two bathtubs!”

Readers of Why Do I Drool? might also want to read Why Do I Poo? as it continues the digestive process.
