In Terry Pratchett: Choosing To Die, world-renowned author Sir Terry Pratchett explores the realities of medically assisted death. Diagnosed with a rare form of early onset Alzheimer's disease in 2008, Terry considers how he might choose to end his life as his condition progresses. Terry meets men suffering from degenerative conditions and is with a British motor neurone sufferer as he carries out an assisted death at the Dignitas clinic in Switzerland.
Sir Terry says: "I am a firm believer in assisted death. I believe everybody possessed of a debilitating and incurable disease should be allowed to pick the hour of their death. And I wanted to know more about Dignitas in case I ever wanted to go there myself."
Sir Terry has said that he would like to choose to end his own life rather than succumb to his degenerative condition. However, he acknowledges that there are a number of people who are against assisted dying for religious, moral or practical reasons and at present, assisted death is both an ethically contentious and illegal act in the UK.
In a moving BBC Two documentary, Sir Terry meets those who, like him, would like to control the way they die.
