They weren't doing what they considered to be "harm." It was as much as they had to offer then. It was not all that long ago that acne was treated with radiation, for example. It worked, but a lot of the patients ended up having other medical problems later.
"Blackbird" is one of my favorite songs as it is. Shown in this context and I could barely talk for about 5 minutes after I watched it. So terribly sad.
Having just watched the video about the young woman who has cerebral palsy, ran a half marathon and came in last - but still won everyone's hearts - this was a very appropriate song.
What an awesome guy.
