James May's 20th Century ep03 Body FantasticJames
James May discovers just how far he can push his body, and explores some of the most remarkable medical advances over the last hundred years. He begins by testing himself in a centrifuge - a devilish machine that is used to train fighter pilots and astronauts. As the pace picks up and the 'g-forces' increase, he dramatically passes out. Then James is invited to watch open heart surgery - where a man's heart stops beating in the middle of an operation. Fortunately, it is all part of the procedure to fit an artificial heart. But his biggest surprise came when he investigates the 20th century's greatest medical breakthrough - the discovery of DNA. James has his DNA tested, only to discover that he's not quite as English as he's always assumed.
