As far as humanity goes, we live in a whopper of a different world than our ancestors did. Want something to eat? Chances are pretty darned good that it's only a few steps away in the refrigerator or cabinet. Cabinets empty? Go to the store, or a diner. Refrigerator empty? Same advice. It's pretty simple really. Nowadays, we can pretty much have whatever we want as long as we can pay for it.
