This book is a really good book. It tells you stuff that you don't need to know, but its all quite interesting. It's weird because it's quite strange and is very good if it answers something you wanted to know.
There are more books written by the same author: Why eating bogies is good for you, how to avoid a wombats bum, why do farts smell like rotten eggs (these books are nothing like, Why does ear wax taste so gross!)
