This week we're exploring what science can tell us about happiness. We'll speak to John Helliwell, Co-Director of the Canadian Institute for Advanced Research (CIFAR) Programme on Social Interactions, Identity, and Well-Being, about the World Happiness Report, a global project that uses tools from economics, psychology, health statistics and more to study the happiness of people and nations. And we'll speak to journalist  Michael Booth about his book "The Almost Nearly Perfect People: Behind the Myth of the Scandinavian Utopia."
