I've found this available to read online for free at

On the subject of dental cavities - "These data reveal an average increase in susceptibility of thirty-five fold." The average man in the 1930s, who was a hell of a lot healthier than the average man in the 2000s, was 35 times more likely to have dental cavities.
On fertility - "Almost everyone who studies the matter will be surprised that such clear-cut evidence of a decline in modern reproductive efficiency could be all about us and not have been previously noted and reviewed."
Back in the 30s, they were worried about their reproductive success relative to the primitives. Our sperm count has dropped 50% since the fifties. Food for thought.
The Eskimos never had doctors, and "healthy" people over here come down with a cold every few weeks.
