I think there used to be way more of everything in food and the environment in times past. Also there used to be way less toxins. Combine those two and you get deprived people.
No wonder our medical costs are ski rocketing. No wonder there is so much violence, ADD, autism, etc. Now wonder there are soooo many, really a ridiculous amount, of people with chronic diseases.
Look around you, at work, in your family: how many people have pains, fatigue, foggy brains, buffalo humps (most women over 40 show signs of them), brown spots on their skin, etc, etc.
There are very few people now growing old healthily.
