On the History Chanel show, The Story of Us, they said people who lived in the country were healther than in the cities without indoor plumbing, lots of outbreaks of colera, flu, pnumonia. Indoor plumbing in the cities helped clean the up. They said we were actually healthier and richer than the average Britton. I think the Bible says 3 score and 10, which is 70 and if by reason of strength 4 score, which is 80. That is where we are now.
I don't think it is as much what you eat as to how much without hard work. Hard work that farmers once did, burned the calories off, and all the pork and fat didn't bother them so much. Today, it stays on you and causes heart disease, strokes, and diabetes. No hard work, eat less. Back to meat storage.
