If that even comes close to the truth, we're a very different country from what we were a few decades back.
And I believe studies show in the ‘60s, cerca to then, we were a much leaner nation. So, maybe one difference of many would be processed foods.
I also see a bit of what is called Appalachia on here. Not sure what the significance of that would be. I have seen some of the so-called “backwaters” but on the other hand, every state has their rural areas.
