the point is that certain people have higher resistances to damaging practices than others. This guy lived one of the worst lifestyles ever and still looks completely healthy and has more energy than almost anyone I know.
Well, maybe eating thawed meat isn't as damaging as you may think. Humans did go through an ice age, remember? Also, Inuit's have been known to eat their food frozen:
"Vitamins and minerals which are typically derived from plant sources are nonetheless present in most Inuit diets. Vitamins A and D are present in the oils and livers of cold-water fishes and mammals. Vitamin C is obtained through sources such as caribou liver, kelp, whale skin, and seal brain; because these foods are typically eaten raw or frozen, the vitamin C they contain, which would be destroyed by cooking, is instead preserved."

Maybe as Cherimoya says, some people can handle frozen foods better than another. Being fairly light skinned may have something to do with this? I say this because people with light skin are said to come from northern latitudes while someone who is darker is said to come from areas closer to the equator where the sun is always shining. It has been proven that darker skinned people need much more Vitamin D than the light skinned. It's been hypothesized that because of the lower intensity of ultraviolet light that comes from the north, the light skinned need less Vitamin D. I would even throw in the fact that the light skinned wore more clothes - hence another reason why we may need less vitamin D. Also, people with light skin can produce their own Vitamin D via the kidneys. My point is, because I'm light skinned the gene's that handle my digestion may be more suitable to such cold food.
