RE: The Amish are gonna win.
An old cooking show I happened to watch a couple of times:
Amish Cooking from Quilt Country: With Marcia Adams.
Can’t remember the amount but she said the Amish men did so much sawing, lifting, carrying, pulling, plowing and harvesting tasks all the daylight hours without machinery and labor saving devices that they could eat 8,500 calories (I think) a day and never gain an ounce of weight.
there aren’t many fat ones, but the inbreeding is taking a toll.
