I don't know the answer to that question, but I do know what we need to do to make it even possible.

There was a powerful article in the paper last week which described the author's involvement in the death of a number of people over the years, who (according to the author) sought his help to end their lives. It was heartfelt I believe and made gripping reading. Especially since it ended with the author's own journey to Switzerland to end his life.
