The way to make better, healthier physicians and improve society is to re-humanize their training. I really think teaching the humanities is a way to keep their emotions alive, not succumb to the tunnel vision that comes with a technical education. Explain how you develop your patients into characters. That's the beauty of nonfiction. It's a burden and it's a blessing.
Readers are inherently interested because they know it's true.
For example, if I made up a story about a black quarterback who won the Heisman Trophy and married a beautiful blond woman and then slaughtered her in the driveway and got acquitted, as fiction that would be mundane because it would be unbelievable. But look at how it attracted us as nonfiction. You revealed that David, the main character, had been fantasizing about an old girlfriend even though he was living with another woman. They sat down with me for hours on end and gave me their stories. I gave both of them the chance to read the manuscript and make changes, and in both cases there were things in the manuscript they didn't know about.
