Yes I am. And yes I would (accept a transfusion, that is.)
I am A- which is somewhat rare, and I am called regularly. I had to put a stop to it because I was so wiped out after donating (made ME anemic) that I only donate on an emergency basis - which seems to be around every holiday.
It did take a while to come to that, but it was my final rebellion against the bOrg.
