was when we quit hunting and started farming. Pretty much everything about us has gone downhill from there such as poorer health, more disease, higher mortality, and the list goes on. It was mainly due to less exercise and poorer diet. I was just reading a science journal article about it the other day. For example, our average height dropped 5 inches when we switched to agriculture. Our average life span dropped too. I don't remember how much, but it was significant. I had no idea it was that bad.
In the end it means our bodies are built for moving around, not sitting on our butts. We should all do more of the former and a lot less of the latter. Lighten up on the cheeseburgers too.
