Ironically... My wife had to have her colon removed many years ago and she needed to build up a reserve of blood for the operation. Each time I donated (and to this day) I typically throw up or pass out when they drain me. I don't know why except to believe I don't have enough oxygen floating around my turkey brain in the first place...
But to see wrecks, accidents, murder scenes and other bad things, I have never had a problem, except to feel great sorrow for the victim.
