From Afternoons, 3:08 pm on 7 November 2017

20 years ago, a complete stranger risked his own life to save the life of psychology researcher Abigail Marsh.

Marsh looks at the biology of altruism in her new book The Fear Factor: How One Emotion Connects Altruists, Psychopaths, and Everyone In-Between
