When I asked Fred Whiteman how old he was, he replied, "I'm 47 on the outside, 31 on the inside.  I've had more trouble that most senior citizens, and I still look at life through the eye of a child."  What kind of an answer is that?  Chronologically, Fred had seen 47 birthdays.  Within his chest cavity beat the heart of a man 31 years old--the result of having had a heart transplant.  Has Fred really seen more trouble than most senior citizens?
