Nell Burger Kirst, a 4th year medical student at the University of Michigan, tells a memorable and important story in the March 31st New York Times: Comforter and Comforted relates the story of a person who is called to be a "care giver." Little is written about this important human subspecies, yet they are the substructure of the entire health care system. Some are unlikely candidates.
Please read Nell's vignette. It's a keeper!
