O Rh - Negative blood type, are you one?

O- blood type has come up in a couple THC episodes. I was wondering if there was anyone else on the forum was too. The only strange thing I can say about it is I swear I can sense / know when I meet another person who is O- after meeting in person. I know the other person is O- because of the instant connection we both seem to feel in each other’s presents. With about 2.5% people being O- when you bump into one it can be a strong “thing”.
