Research shows that happy people live up to ten years longer than unhappy people. But what is happiness? Who gets to be happy? And how do they achieve it?

Gyles Brandreth found the answers when he set out on a journey looking for happiness and ended up in the psychiatrist's chair - with Dr Anthony Clare. And in The 7 Secrets of Happiness he reveals that the secrets are simple, easy to remember, but challenging to achieve.

This is a book that won't simply enhance your life: it will extend it.
