"You should read this funny, stimulating and rewarding book. You'll be happy you did." —Guardian

The pursuit of happiness is one of the most enduring quests of human life. But where does happiness come from, why do we need it, and what does it have to do with the brain? In this delightful sequel to Idiot Brain, Dean Burnett combines cutting-edge theories of the science of emotions with interviews and contributions from relationship experts, psychology professors, comedy writers, celebrities, and pretty much anyone else involved in bringing about happiness in others. Witty and perceptive, humorous and enlightening, Happy Brain explores a fascinating aspect of modern neuroscience, and in the process discovers something about what it means to be human.
