Terry Pratchett: Choosing to Die (TV)

In this documentary Terry Pratchett discusses his Alzheimer's and how it is slowly eroding away his life and his talent. He meets others with medical conditions which will inevitably lead to a prolonged, painful and above all undignified death and asks the question "is it better to end things early?" There are few answers here. Pratchett is on a genuine mission of inquiry, he's not preaching a position, nor does he end up with an opinion. Instead he takes a frank look at a subject most shy away from, and his only real conclusion is that we'd perhaps do well to think it through more than we do now.
