How can we stay sane on a planet shrouded in chaos? How do we stay human in a technological world? How do we feel happy when we are encouraged to be anxious? Matt Haig has been a pivotal figure in the conversation about mental health since Reasons To Stay Alive, a book which tells the story of how he overcame the illness that almost destroyed him. The follow-up, Notes On A Nervous Planet has been described as, ‘an honest and human guide to coping with the modern world’ and has become an essential for people all over the world. Drawing on his own experiences, he links what he felt with the world around him and shares his reflections on how we can feel happy and human in the twenty-first century. He talks to broadcaster Claudia Hammond.
