The Happiness Project

In the concluding programme of this 25-part series, Martin Sixsmith looks at where we are now in terms of understanding what makes us think, feel and act the way we do.

He re-visits the Government's 2010 pledge to increase happiness and well-being and talks to former 'happiness tsar' Richard Layard. He examines initiatives such as the provision of thousands of newly-trained CBT therapists to make treatment for mental health problems more widely available and other ways in which we are being encouraged to modify our behaviour, asking 'what is happiness' and whether it's achievable both for an individual and society .
