When Daniel Lieberman goes on research trips to remote locations in Kenya and Mexico, he’s the only one getting up to go for a run in the morning.
Why? In those cultures, people get plenty of physical activity as part of daily life; they don’t need exercise. But Lieberman, 56, a professor of human evolutionary biology at Harvard, has all the conveniences of modern life in America. He relies on running to get the physical activity he needs in a day, especially during the COVID-19 pandemic. (Plus, he likes it and is usually training for a marathon—his PR is 3:20:16 from the Bay State Marathon in 2015, and he has run the Boston Marathon 10 times.)
Our bodies developed to work best with lifelong physical activity. But our minds “never evolved to get us moving unless it is necessary, pleasurable, or otherwise rewarding,” he writes. “Plunk us down in a postindustrial world, and we struggle to replace physical activity with exercise—an optional and often disagreeable behavior.”  When Daniel Lieberman goes on research trips to remote locations in Kenya and Mexico, he’s the only one getting up to go for a run in the morning.
