GREAT article and content. I strongly suggest the book "born to run". There the author describes the "Tarahumara" people. They don't eat diverse food and they drink too much of their home made alcohol. The way the do economics is by sharing - but not by force or "living for others" as Ayn Rand describes altruism - but by choice. There are no diseases, no cancer, not injuries and they can run for days straight. They grow to be very old. :) Very interesting book and people.
