If anything, I think our largest (modern) collective societal health problem is that we do wayyyy to much trying to avoid straining the heart. For how much of human history were we not working mostly sedentary? It has a cost. The body is meant to be worked. It loses strength and stamina when it isn't. I don't think the answer is to do even less. Besides, do you know how many involuntary naps I'd take if I was laying down all day?
