"Humans are not made to be sitting for the 10 to 11 hours that, on average, we do (and these 10 to 11 hours are in addition to sleeping)," he added. "Our evolution teaches us that our bodies are made to hunt and run away from our predators, not sit in front of a screen. We have completely ignored this side of our nature; therefore, it is not surprising that our bodies accumulate too much fat, get heart disease, cancer and type 2 diabetes. All these are direct consequences of too much sitting and not enough physical activity -- both, not either/or."
