I'm confused. In your book ER4YT, you stated several times that O's live longer. Now I'm reading that B blood individuals attain more advanced age. I have found much of your work to be contradictory, Why? ANSWER
You make it sound as if that were a bad thing. A lot of data is contradictory; that is just one of the delightful aspects of science, and especially the science of epidemiology. That is what distinguishes science from other intellectual pursuits. The study (1) that I was aware of much earlier, looked at elderly Italian doctors and concluded that there is an excess of group O. This other study (2) asserts that it is group B that is longer lived was just one that I came across much later. Which is correct? It is hard to say, since the indigenous diets may or may not fit the profile diet for that type as I recommend it.
