Disgust has graduated from forgotten emotion to hot topic for scientists and the media. This book tells how disgust evolved from a parasite avoidance system in animals to a powerful emotion governing our everyday life, relationships, manners and our morality. Disgust is an ancestral voice in our heads, telling us how to stay healthy, who to get close to and who to shun. But such voices may not be our best advisors in the modern world. 'Don't Look, Don't Touch, Don't Eat' teaches us how emotions direct our lives, but also that we have to better control and channel our revulsions.
