Daniel E. Lieberman On How Civilization Makes Us Sick
There’s growing attention to the importance of nutrition and physical activity, which is a cause for hope, but my concern is that these trends are very much class driven. Wealthy people tend to be able to afford to be physically active and to eat healthy foods and to reduce stress and to get enough sleep and to stop smoking. There have always been disparities in health between classes, but I worry they are going to widen. Just as we have income inequality, we’re heading toward a world in which we see an increased burden of noninfectious chronic diseases in the lower classes.
