Results: Blood Types, Personalities, and Alien Blood

Because my disease requires so much blood work I have taken an interest in the study of blood and have come upon some really interesting and even freaky information. Some believe that whether someone is Type A, B, AB, or O determines personality, a belief particularly prevelant in parts of Asia. Where it really gets surprising is with the Rh positive vs. Rh negative factor because the minority of people with Rh negative blood (no more than 15% of the population) is different from the vast majority of the human population in physical ways as well, which primarily affect blood tranfusions regardless of the letter of the blood type and pregnancy in Rh negative women inpregnanted by Rh positive men. However, there are other physical differences that when combined with the fact that scientists can't figure out where Rh negative blood came from have led to speculation that Rh negative blood is of alien origins. What are your thoughts on this?
