““A recent study in the American Journal of Epidemiology followed 123,216 subjects over fourteen years and found that men who spent more than 6 hours a day sitting were 17 percent more likely to die during that time than men who sat for less than 3 hours. For women, the increased risk of death was 34 percent. This increased mortality persisted regardless of whether the participants smoked, were overweight, and—this shocked me—regardless of how much they exercised. Humans aren’t built to sit all day.””
