Mark Lawson talks to explorer Sir Ranulph Fiennes about his life's work. From being bullied at Eton to the death of his first wife, Fiennes reveals the ingredients behind his incredible determination and exploits. At age 65, after a heart attack and several near-death experiences, retirement is far from his mind - 'I would find it pretty difficult if there wasn't always an expedition in the planning... it would be the beginning of a pretty quick end I think you know, as with lots of people who retire'. He is currently looking for sponsors for his latest expedition, but remains tight-lipped as to what it might be. Like before, he wants it to be a first for England and to beat the Norwegians.
