I remember my grandparents and the hired hands they had working for them. Their diets were exactly what the “experts” say is killing us now and most lived into their 80s and 90s. One of my doctors told me about a study a doctor friend of his had ran. Took 3 sets of chickens and put them all on a high fat diet. Then put one group on no exercise, put one on moderate exercise and put one on hard labor. The group on hard labor outlived both other groups by a substantial margin.
Someone has to ask ... how does one put chickens on "hard labor"?
