2. Happiness

Karl Pilkington tries to find out how people achieve happiness, something he isn't sure it is worth pursuing. In Mexico, he joins members of a tribe who enjoy running ultra-marathons and meets a group that finds pleasure in pain. In LA he hangs out with some hip-hop clowns, experiences a day of beauty with a plastic-surgery addict and gives up his possessions to see if the simple life is the answer to contentment.
