The thought of a heart and lung transplant must truly be overwhelming.

I know a person who had a lung transplant (and pancreas I believe) and he is a new person today. He was a very fragile diabetic who really didn't have much quality of life. He is no longer a diabetic because of the transplant, and has such improved health that he says he is "normal for the first time ever."

So, as extreme as it may seem (and yes, it is an extreme measure) it really could be one of the best things you could do.
