In today’s talk, Nilofer Merchant gives a startling statistic: we’re sitting, on average, for 9.3 hours per day—far more than the 7.7 hours we spend sleeping. “Sitting is so incredibly prevalent, we don’t even question how much we’re doing it,” Merchant says. “In that way, sitting has become the smoking of our generation.”
But there are consequences. Physical inactivity, Merchant says, leads to upticks in our risk of breast cancer, colon cancer, heart disease, and type II diabetes.
