My father waas a psychiatrist. Once, long ago when my EMT cert was current, I was visiting him when a neighbor came over clutching his profusely bleeding hand. Dad just looked at me and said, "I think this one is for you, son".....He was a very able assistant.

Nurses seem to be everywhere. I was presenting at a national archaeological convention many years ago, when a very obvious Thunk! interrupted my sterling presentation. It was my very good friend and assistant going into a grand mal seizure. As I reached his side, a lady identifying herself as a nurse appeared out of nowhere. What was a nurse doing hanging out with arckies?

Same thing happened at an auto accident when I was out on a run. Just as I reached the vehicle, another nurse showed up. I don't know how they do it, but it's great.
