I came here to say thank you for posting as well. You are so right: "this is a fate that most of us will face (if not directly, on behalf of a loved one)". If you'd care to read a bit more I highly recommend this controversial book based up on a true story: 'Love Life' http://www.amazon.com/Love-Life-Ray-Kluun/dp/B003IWYKD0 Edit: A film was made as well, called 'STRICKEN'.
