> I'm pretty confident in stating that the average Chinese has overall better immune system function.

I would disagree with this, especially in Southern China in the winter. The lack of indoor heating has a huge impact on your immune system, to the point that it is extremely easy to get sick.

There is a reason a bunch of old people die in Hong Kong whenever the temperature drops below 5C, which is much more developed compared to the rest of southern china.

Yes I'm sure there are other factors, including pollution etc. But wrt. to Covid the main risk factors seems to be blood sugar / blood pressure problems. Possibly because these are most correlated with immunosupression, various deficiencies, possibly immunosupressive medication (to mitigate chronic inflammatory conditions) etc.

Actually, the main risk factor seems to be age, which is also why Hong Kong was hit so hard. Otherwise, I don't think we can say much about the difference between Chinese and western comorbidity risk factors...not without data anyone we are not likely to get access to.

I think that is because age is often correlated with those ailments? Wasn't there a stat about a vast majority having 4 or more comorbidities?

I agree, we won't have data, but my gut feeling, having been raised in this kind of environment, is most people are basically poisoned by such lifestyle factors. 88% percent of Americans have a metabolic dysfunction. Again, I agree we couldn't prove this in a satisfactory scientific way, just what my eyes are seeing.

American life expectancies are still significantly higher than Chinese ones. Now, that could just be correlated to healthcare resources (America spends a lot, Chinese spends much less and much of it is wasted on pseudo medicine), but environmental factors also come into play (air pollution must be having an effect already).

I just looked it up and the difference is about 2 years? Apparently the difference is spending is 15x or more. I also think many Americans are kept in a bad state of health for a long time in this healthcare system, and that older Chinese might have a slightly lower life expectancy while also being in better health.
