Good thing my blood type isn't O. That's the one that can be given to anyone IIRC. At least I won't get told to GO AND GIVE BLOOD BECAUSE AMGD YOUR TYPE IS O GO SAVE SOME LIVES SON
My mother is O-positive.
I'm unknown because the information is missing.
But at least I'm not blood type O. I'm either blood type A or B.
So blood type O is rare... apparently.
