Counselling & Psychotherapy: The Happiness Formula - What is happiness?

Mark Easton goes on a journey to understand what lasting happiness is. The six-part series looks at the newest research, examine the latest policy proposals, and meet the most cutting-edge thinkers from around the world.

We journey to the Himalayan kingdom of Bhutan, which is the only country in the world that puts happiness at the heart of government.
