I'm interested in what you have researched. As a medical professional I've only ever known blood types to only indicate the absence or presence of antigens and antibodies in the blood stream.
According to theABO system, there aretwo antigens (A or B) and two antibodies (A or B) found in human blood. All humans can be typed with having antigen A with antibody B, antigen B with antibody A, both antigen A & B with no antibodies, or no antigen (O) with antibody A & B.
The Rh system, on the other hand,is based on the presence of Rhesus antigens, more specifically the D antigen (RhD), and is indicated on a persons blood type as either positive (+) or negative (-). RhD is responsible for provoking an immune system response for the five main Rh antigens.
I have seen dietitianstry to use blood types as a way to tell people what their ideal diet should be to help them maintain a healthy lifestyle and all of thatresearch has beendebunked. Your blood has much less to do withyour personality than your DNA does. Personality is based off of multiple factors including genetics, environmental and social factors, trauma, and more. Blood has nothing to do with your character and has much more to do with health.
Additionally,It's not all that uncommon for those with "mismatched" blood types to have successful relationships. Blood type only really matters if you're trying to have children. (+ vs -). If mother and child have different RhD then the result can be fatal for the fetus if fetomaternalhemorrhaging occurs.
I see what you mean. My aunt on my biological fathers side is a nurse practitioner. However, like almost many things in the world. There is not always a for sure theory. (This is what makes science one of the most interesting topics).
The sites I've been on are mostly theory. The reason I wrote the article was due to how accurate it was to my personal issues and etc.
I have been told to stay in my lane, as technology is my big area. I am just researching outside to discover new things.
It's hard to argue that blood typing and its uses are just a theory in terms of medicine and science when there is factual evidence. There is a clear distinction between fact and theory. Facts can be observed or measured objectively. Theories are interpretations and explanations, which are subjective to one's perspective .
Typing blood for the purpose of blood transfusions is essential to say the least, as it is a crucial step in performing the procedure safely and successfully without fatal side effects. This cannot be disputed. Typing blood to perform a personality test on someone doesn't exactly make a lot of sense without substantial, irrefutable evidence. The same goes for saying that, "Every Taurus is stubborn." or "Every Cancer is emotional." General definitions of a label may apply to most people, but putting everyone that fits that label into a stereotype based off of those descriptions is a regressive way of thinking, in my opinion.
I don't mean to say, "Stay in your lane". What I mean to say is understand the difference between fact and opinion. A lot of new age pseudoscience tends to pass itself off as factual data, but the reality is that it's a bunch of people confusing philosophy with science, or looking for extraordinary answers from ordinary things. Science can be beautiful yes, but we're not always going to get the answers we want.
