Book excerpt: What’s worse than finding a maggot in your apple? Which smells worse: a rotten egg or a rotten leg? What are sick and poo made of? Glenn Murphy, author of Why is Snot Green?, explains how being revolted (and sometimes being revolting) can be both brilliantly beneficial and stupendously silly in this fantastically informative book. Packed with illustrations, photographs, information and jokes about all sorts of disgusting things, from bugs, bacteria and sweaty armpits to exploding bodies and creepy-crawly creatures, this book contains absolutely no boring bits!
