We humans have an remarkable ability to survive almost anything. As a species, we are indeed a truly special animal.

We are today attempting to become a kind of 'opportunistic' feeder, I guess similar to the dog, rat and pig, however unlike those animals, we are simply not as well equipped for the mixed diet. Our limited ability to tolerate and live on a mixed diet, especially when meat-deficient, brings massive health problems to the modern human.

Resorting to short periods of minimal quantities of vegetable foods,eaten in order to survive periods of poor prey availability, beginning in the later part of our paleolithic period certainly was of great benefit for human survival and migration. However that is NOT the optimal or best diet. Unless faced with starvation, we are all better off avoiding eating mixed.

Stefansson spent many paragraphs, in several of his works describing the extraordinarily thick and strong bones all Inuit people had, especially their skulls, one of the thinnest and lightest for its strength of the human bony structures. How can anyone give a moment's credence to anything said by a 'researcher' who claimed otherwise?

By the way, I have only suffered one fracture in my life, I fell 15 feet onto hard dirt, landing on my hands and bum- from a scaffold while moving a PA system, in 1974, at the age of 39. I broke my left ulna at the wrist joint. It healed very rapidly, I took the cast off in two weeks, the brace off in a month. I cannot even tell it was ever broken.

Last August while tensioning an aerial electric distribution cable on the edge of a roof 12 feet up, the anchor failed and I was jerked off the edge and went straight down, landing on my feet. No damage other than a slightly sprained muscle in my lower back, and one displaced vertebra necessitating a trip to the chiropractor. I have extremely heavy, dense bones at 71- like an Inuit. Could any of you reading this NOT have expected to have broken something?
