Actually encountered: Altitude sickness, many times. Some serious enough to require relocation to lower altitudes. Dehydration many times, resolved by drinking fluids and resting. small cuts and abrasions. I am thinking and thinking....and that's it.

Yeah, we carry more than just the stuff to treat those. But we also tend to travel off the beaten path, which means we are less likely to be called in to help someone nearby. And we seem to be pretty careful, so far nothing even remotely serious has happened to us.

Neither of us is a trained medical professional of any kind, although we've taken a few CPR/First Aid certifications over the years.
