Blood group AB or O?

I was just thinking the other day... (I'm always thinking, actually). If you were given a choice to actually pick your own blood group, would you pick AB or O? I'm not talking about A or B. Just AB and O. Sure all of you studied it in science or bio. AB is the universal recipient, and O is the universal donor. Most people would say: O, of course!! Why? Because I'm noble and kind and I LOVE donating to people to help them. Maybe some would go for AB... acknowledging the fact that they are in reality, a selfish person. The thing is? Why bother thinking about it at all? Whether you would pick AB or O, it doesn't matter, because you're stuck with whatever blood group you have!! Just kidding. What I mean is that, whether you're kind or selfish, who cares? Be yourself and don't pretend to be someone you are not. HYPOCRITE.
