Psychologist Kimberley Wilson and Dr Xand van Tulleken take a journey around the human body, to find out what it can tell us about our innate capacity for change. In this episode, Kimberley and Xand focus on the heart, which has been branded the seat of emotion by generations of poets and songwriters. They find out whether it’s medically possible to die from a broken heart, hear from a woman who lived for 16 months without a human heart, and Xand opens up about how Long Covid is affecting his heart.
