O+ fer me. The main reason I know this is because when I was born, I was the third child, and if I'd been a boy they'd had to do a transfusion. (Least that's what mom said) She had the RH- Factor thing goin on.

Rh- is a fairly rare type  of blood. When they have blood drives they are always happy to see someone with that type. Mom never could donate blood because she had Hepatitus as a child and they won't allow anyone that's had it to donate.
