Facts and Myths

First published in 1990, Happiness is based fairly and squarely on scientific evidence and provides realistic insights into the following questions: What is happiness? How can you tell if you are happy? How important are love, sex, money, and family relationships? Can happiness last? Is there a blueprint for happiness? Is unhappiness a terminal illness? Is there a ‘happiness gone’? This book will be of interest to students of psychology and other mental health experts.
