WOW! Thank you for sharing. I may have to post a link to your blog on my friend feed, so that others can see this.
It reminds me of a movie I saw years ago about Gale Devers. She won Olympic gold in track/field. She then got to the point where she couldn't walk - the doctors wanted to remove her feet even, I think. She refused. She started out walking inches, and eventually won Olympic gold - again.
