Book excerpt: With unflinching honesty, an ER doctor tells readers what it's really like to be a caring physician with one of the most demanding, exhilarating, frustrating, and rewarding jobs in the world. An emergency medicine physician for nearly a decade, Dr. Pamela Grim has delivered babies, treated heart attacks, saved car accident victims, comforted the dying, and consoled the living who were left behind. She has worked all over the world, caring for victims of gang life in America's inner cities, victims of the war in Bosnia, poverty-stricken patients in Nigeria, and bank presidents in the United States. Relating these rich and varied experiences with compelling prose, Dr. Grim takes readers into the E.R. and lets them experience first-hand what it takes to make split-second, life-and-death decisions in the course of an average day.
