Weirdly enough, my *uncle* was also named Oxidant.
Blood type A has some survivability to Bubonic Plague, type O does not. So the O’s died out and the A's took over in the middle ages.
Mitigating factor is that O is recessive, so two people with A, can actually be A/O and produce an O child.
But A seems to be susceptible to cancer and heart problems. Where O is survivable of a heart attack or cancer.
The rare ones like B and AB are quite different. B's tend to die of stroke, and AB has a lot of problems with autoimmune diseases: Lupus, etc, and stroke.
Now these are generalizations. You can have cancer and a heart attack and be an O....if you smoke and have other self inflicted habits.
That is why certain diseases tend to run in families, their blood types are the same.
I challenge you to look around and ask questions.
My friends think I am nuts.
