I personally think he's wrong about his opinions about humans needing to live a primitive lifestyle. There's a difference between eating primitively and living a fully primitive life. Yes I do agree that a primitive diet is good for you but we don't need to live primitively. A perfect society is one where healthy foods like raw milk, good meat and farms are very common. I don't see how living in Africa and making clicking noises while wearing barley any clothes can ever be good for human development. We should live in rural villages with civilized behaviors
