1/ This is a very good and well research piece but I do not agree with one major part of what you wrote. Lack of immunity simply does not work the way you describe it in relation to Native Americans, Aztecs or how it is portrayed in book "Guns, Germs, and Steel”.

2/ I believe you have missed the most crucial part when doing a research on that topic. Body robustness and grain based societies are keys to understanding why Native Americans and Aztecs were decimated by diseases. The reason why many fell ill and died from diseases brought by..

3/ Europeans is not because of lack of immunity, but because of nutrient deficiencies thanks to farming practices / grain based diets. This has created less robust bodies and weaker immune systems which essentially caused them being more prone to "new" diseases.

4/ Your immune system simply cannot learn or respond correctly if the body is deficient and not strong enough. If they had not been in poor state of health, which is what has happened to many human populations across the globe after agricultural revolution, then..

5/ even "new" diseases for the immunologically naive populations would not pose any problems. The same story can be observed worldwide over and over again. When war and famine comes, diseases and epidemics follow.

6/ When new stressors arrive, for example thanks to Industrial Revolution, pollutants, new manufacturing and food processing methods, body is unnaturally being drained from nutrients (or not being provided enough), which creates epidemics of infectious diseases in those who..

7/ are the poorest, weakest & most deficient. Disease fighting process & inflammation even in itself drains nutrient stores from the body, so if there isn't even enough to facilitate defense processes, then the body is in big trouble.

8/ That is exactly why a frail elderly person may die from a disease like flu, even when they were basically immune to it their entire life. A lot of people make a mistake by dismissing the nutritional aspect and its direct relation to immune function and overall health.
