I have spoken about donating blood to save a life before. We had our blood drive today, but I am going to bring humor into it. I go through the list of the drugs that may preclude you from donating. Then they ask you to state which sex you are. In my case it is pretty obvious. Then they ask if you were born in certain sub-Saharan African countries. I look at my skin and shake my head.
Then I can't resist more silliness. The vampires will stick you and take your blood. Probably not clever, especially when you lay back and they are armed. You even get to bleed on command. Thirty-one people went to give blood, twenty-three were successful. Shucks, unsuccessful in donating blood.
