I hate to burst anyones’ bubble but I can truthfully say this is a load of rubbish. I am O-neg and have been HIV-pos since 2001. The virus makes NO distinctions!!!
I had heard the same thing, but it was a general thing about being immune to viruses. I don’t think its true. But I have no evidence or proof. I do have an extra vertebrae and one more set of ribs that my doctors weren’t expecting, though. But I don’t have a tail like some others I know.
