Hey there... I wonder about all of those same things regarding our blood. I am a rabid researcher, and find it... "interesting" that so little is apparently known or stated regarding the anomaly that is our blood type, other than silly pop culture fluff about how we must be descended from "aliens." We Rh negs are definitely made of something different in body, mind, and soul though. It's so refreshing to connect with other Rh negs. Hope you're having a great week so far
