In this exciting and very approachable overview of the relatively new science of happiness, award-winning writer Klein brings together a wide range of fascinating research from the worlds of neuroscience and social psychology and uses it extremely intelligently to emphasise the many factors that give us our greatest chance to live happily and well. There is a strong emphasis in the book on the value of community, work and sociability. The neuroscience is particularly well presented with constant reference to everyday experiences and situations.
