Here's a Cordain quote: "In most hunter-gatherer populations today, approximately 10-20% of the population is 60 years of age or older. These elderly people have been shown to be generally free of the signs and symptoms of chronic disease that universally afflict the elderly in western societies. When these people adopt western diets, their health declines and they begin to exhibit signs and symptoms of 'diseases of civilization.'"
