When I went to Amazonia, l went as the field doctor for biologists studying crocodile behavior. There's no way humans should have any encounters with crocodiles. You should stay away from them!
Even as a kid in the Bronx, I wanted an adventurous life.
Every time I've been on Everest, people have died, though not in any expedition I was part of.
The basic thing with adventure medicine or extreme medicine is that you are going to places where humans don't belong and people will certainly get into trouble.
