There are so many titles I could give Mark because he's done so much and continues to press on and live life to the fullest and that is the main theme of his message.  We had a very fruitful discussion with Mark about his challenges as a youth, having gone through a double lung and heart transplant, then becoming the first man in history (as far as we know) to run a marathon with another person's heart and lungs.  But I think more importantly we focused on the message Mark is trying to put forth in the world today and that is ... well you have to listen to find out.  Hope you enjoy!
