He's determined to have the option of choosing the time and place of his death, rather than enduring the potentially horrific drawn-out death that Alzheimer's sometimes brings. But Britain bans assisted suicide, and Pratchett is campaigning to have the law changed. As part of this, he has visited Switzerland's Dignitas clinic, an assisted suicide facility, with a BBC camera crew, as part of a documentary will include Britain's first televised suicide. Pratchett took home Dignitas's assisted suicide consent forms." Link to Original Source
