Rich people everywhere tend to develop healthier habits—on average, they exercise more, eat better, smoke less, and are less likely to suffer from obesity. Rich people can afford the treadmill, the organic avocados, the yoga classes. And they can buy these things in any corner of the United States. For the poor, the story is different. For the poorest Americans, life expectancy varies tremendously depending on where they live. In fact, living in the right place can add five years to a poor person’s life expectancy.
