I read about Polycythemia vera on Wikipedia and two other medical sites. I also read the two articles you linked. Thank you for sharing these details with me. I feel honored. I like your theory about the condition. But it doesn't fully explain the geographical limitations. I know for a fact that some bloody wars happened in in Japan, China, India, Middle East and much of the region. Maybe things like dietary habits played a part too.

I also think the oncology clinic was selling my iron rich blood to their anemic cancer patients

That is likely. I wish there were systems in place where Polycythemia vera patients could simply contact and donate their blood freely for the anemic patients.

Since you mentioned Ernest Hemingway, I had to share this"

Have A Great Day! 😆
