I caught this in a hotel room a few weeks ago. So very sad, but the subject of the story was ready to go and had no hope for improvement or sustainment. His only choice was to end things while he was coherent.
It was a documentary on a subject that I had never heard of before. It was focused on one family/couple. Another story would have been good. Guess they are hard to come by. Over all, good coverage of the story.
