I see he has a PhD in biology but has no references in his post that refer to actual covid-19 data. He refers to one that is about influenza. Which CDC or Infectious Disease experts have said that the correlation he is making is sound. Even he says these are his “musings.” While he may make some interesting points to ponder, I do not think this is a definitive source regarding covid-19 without the aforementioned experts backing it up.
