Michael Mosley's Meet the Humans S01E05 - Culture of Fear

Michael Mosley and a team of experts place human behaviour under the microscope. In the final episode, Michael and scientists Dr Jack Lewis and Dr Jennifer Wild explore the biology of fear and anxiety in the modern world. Fear is one of our most basic human emotions. In the past, it kept us from being eaten by a wild animal. But today, that isn't so much of a threat and yet we live in a state of anxiety - it's becoming unhealthy.
