Today it is hard to know what we should really be scared about. Stand-up comic Jon Richardson, a “self-confessed coward”, is someone seemingly frightened of a wide range of things. In this documentary, Richardson, along with his wife and fellow comic Lucy Beaumont, look into the things that Richardson is most worried that might kill him. Along the way he meets a man who has claimed to have designed a suit that is “indestructible”, learns how to survive a dirty bomb, and meets someone who sells jars of fresh country air for £80 a pop. Jon Richardson: How to Survive the End of the World is on Channel 4 at 22.00.
