Nothing in this article addressed tooth decay or dental formation issues.

Also from the article:

Hunter-gatherers who live until the age of 15 typically experience a lifespan of around 72 years. Among elderly hunter-gatherers, the incidence of diseases such as cancer and high blood pressure is very low. When recalculating the average lifespan excluding child mortality, the average lifespan for hunter-gatherers ranges from 68 to 78 years.

I also never said we shouldn’t follow science or modern medicine.
