With a family history of heart problems, presenter Michael Mosley takes a personal interest in these pioneers, who teetered on the scalpel-edge between saviour and executioner. Michael has a go at heart surgery, meets a man with no heartbeat and witnesses an operation where the patient is cooled until their brain stops and has all of their blood sucked out.
This time, we meet a girl with two hearts, a man who can sing two notes at once, a woman who can bend in amazing ways, a girl who is allergic to everything and a man who can run 350 miles without stopping. These remarkable cases reveal the secret inner workings of our bodies - the ultimate piece of natural engineering.
Xand van Tulleken, Raksha Dave and John Sergeant discover the parallels of the Great Plague of 1665 with the Covid-19 pandemic. Ch1. Outbreak The epidemic is traced back to its source in the parish of St Giles in the Fields, now at the heart of London's theatre district. The program also examines the symptoms of the disease and uncovers new research into the plague bacteria that could overthrow accepted ideas about how the infection was spread. Ch2. Decimation Xand heads to St Barts hospital to look back at historical records which show that nursing staff stayed behind and risked their lives to help the sick. Elsewhere, John investigates why infection rates were so different between the rich and poor, examining clothes typical for each group in the 17th century. Ch3. Aftermath Xand visits Samuel Pepys' parish church and discovers the sad tale of the Poole family, who within 11 days lost all five of their children. He also heads to Eyam in Derbyshire, revealing the heroic story of self-sacrifice that saw all 700 villagers lock themselves in to try to stop the disease from spreading to surrounding areas. Raksha Dave trials 17th-century disinfection methods and reveal a surprising substitute that can be just as effective as modern antibacterial cleaners.
