Stutterbug, thanks for sharing your story as well as others.
When I was a little girl my Dad asked me if I wanted to go with him to this center where paraplegias lived as they were doing all sorts of contests (sport related) and my Dad explained to me what a paraplegia was. I watched these people without arms and legs do amazing things with balls, racing in their wheelchairs, etc. My Dad had volunteered to help out.
When I first saw these disabled people I admit I felt scared because it was the first time I was exposed to this type of disability. But after watching them, the fear left me and I was amazed at their attitudes, so positive and they were having fun!
That day left a huge impact on me and how people make do with what they have or don't have. I'm glad my Dad took me with him.
Traveler, Cat Stevens wrote a song many years ago that is similar to the poem you posted but I forget the name of the song.. Duh! I'm getting old!
It's all about the Immune System mixed with a large dose of Positive Thinking and Detoxing Daily!
This song is about my years with chronic lyme since 1995 and being in remission for over 4 years: http://www.youtube.com/watch?v=ds81S61UvPA
