Have you ever donated blood before? If so, how many times and what is your blood type? Once for me. I wanted to see what it was like. It was nice at first until that needle went into my arm. OUCH! I didn't notice much of anything except the soreness in my arms the following 3 days, and a slight bit of numbness. I don't know my blood type since they never sent me my donor card. They sent me this "Universial herO" post card, though. I don't know if I'm O, A- or B-. *thinks...* You?
