I really am not sure what to make of it. Even if I look at it as being accurate, I just have a hard time accepting the premise that a genetic based weapon could or would target two very specific groups who both have slight genetic differences, yet spare two other very specific groups with genetic differences. But one thing that does come to mind is the Vitamin D factor that seems legitimately correlated to a major portion of deaths. It turns out high fructose corn syrup, in addition to being complete poison, causes Vit D depletion. Now with that in mind, at least in the US, HFCS is in everything to the point one must be active in avoiding it. Add in obesity (body fat sucks up Vit D and renders it unusable). Can't be certain, but I doubt there is much HFCS in China. And anyone of Chinese descent who stuck with their traditional diet living in other nations likely would not consume too much either. And any Jew who adheres to their strict dietary laws also wouldn't be consuming much, if any, HFCS. So, while I am just making a shit ton of assumptions here about what people do and do not consume in their diets, and there is almost certainly more at play, I do truly believe this premise overall has at least something to do with it. The elderly aside, the most susceptible to whatever was happening were those who were dealing with metabolic dysfunction of some type to begin with, so its really hard to make any certain call on any of it.
