Claudia Hammond finds out why astronauts' experiences of seeing Earth from space can have profound effects on their feelings towards planet Earth. She talks to astronaut, Michael Lopez-Alegria, and trainee counselling psychologist, Annahita Nezami, about the Overview Effect and how the power of planet Earth may have therapeutic value for everyone back on terra firma. Clinical psychologist, Linda Blair, is one of the judges on the All in the Mind awards. She talks about how to have a conversation with someone who may be having problems with their mental health and what makes a good, empathetic listener. Thomas Dixon, Director of the Centre for the History of the Emotions at Queen Mary University, London, talks about the history of crying and why the stiff upper lip was just a blip in history. Also, Claudia talks to forensic psychologist, Bruno Verschuere, about his research into why we become worse at lying as we get older.
