Sounds like it was a good investment, Chris. The Red Cross stuff is
very important stuff for referees to have, as we have seen from the
Pan Am Games, where a fencer was struck in the lung during practice.
Last year one of my friends on the team was also had his lung
punctured (wearing my named lame! Yikes.) Link for the Pan Am
incident is here:

Right now I'm working with devices used in the hospital, and I get the
chance to converse with the medical staff. I tell them about our
sport and I get interesting conversations going. One of my
conversations with a med student led into how to help a fencer who has
just been somehow injured with a blade. It's critical that the
closest person to the fencer (usually the referee, because you won't
have a med team at small events) be able to stabilize the wound, keep
everyone calm, and know what to do next.

Glad to hear that you're a certified ref. Perhaps I should call you
"Sir" from now on? =)
