I wouldn't call it a burden, but I think there is a certain sort of duty that falls in line as a human being who happens to be thoroughly trained in healthcare and emergency situations. I can say I've been in a number of situations where a medical emergency occurred (ATV accident, physical altercation leading to broken bones, baseball game- unconscious victim) and those without our background panicked and I was able to step in. I honestly almost considered mentioning it as a lifestyle in my original post, so, in my opinion, I think it could be appropriate.
