You have a needle inserted and than blood goes out your arm in to a machine that is like a washing machine and the machine separates out your platelets and platelets look like the color of straw. I can only hope a good and appreciative person receives my blood or at least appreciative rather than a selfish person. There are two types of selfish people. One type knows they are and at least is honest. The worst are the type that kids themselves they are a good person and that they are not selfish. You know those nasty crazy baddies that call you selfish as if calling you that alleviates some of their selfishness, same with narcissist calling you narcissist. The New York Blood Center is very nice and generous (they insist on giving us Mets tickets) and they say the levels are really low and I had plenty of company donating today meaning I was with like mindedhearted people.
You have to squeeze a ball to help push blood out and than rest as the machine returns the part of the blood it doesn't use and it takes around a hour maybe longer. They tape it to encourage zero movement of the needle. As I have told you, white blood cell donation is two hours with a needle in each arm and YOU CANNOT move your body which is hard for me.
