Brand new series from Mark Watson where he reignites his quest to improve the world, nimbly assisted by Tim Key and Tom Basden and with the additional help of the listening audience. Mark asks the big questions that are crucial to our understanding of ourselves and society, and in a dynamic and thought-provoking new format he opens the floor to the live audience and asks them to jump into the conversation via tweets and messages to work out how we can all make the world a better place. In this episode, Mark looks at 'Strength', which comes in many forms. We all need to be strong sometimes in life, whether we're dealing with an emotional fall-out or carrying a really heavy dog to the vet's. Some have inner strength, like people who survive divorce; some have outer strength, like those guys who pull buses with their teeth in competitions. But can strength be - ironically - a weakness? Produced by Lianne Coop.
