Handwashing with soap could save many lives globally. Though most people know it they don't actually do it. We showed how to harness emotions such as disgust to get people washing hands in rural India.
Disgust is a powerful emotion which dictates much of what we do, both in private and in public. Understanding it can help us to understand a lot about ourselves – our seemingly irrational behaviour, as well our feelings and our emotions.
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.
