I read this before going to Nepal for some NGO work a few years back. The premise of the book is that many, many things can be solved with clean water and sleep, and that's helped give me the confidence to explore deeper in parts of the world where there really aren't doctors. Also notable! Don't load people up with antibiotics that aren't needed since that's contributing to increasingly widespread antibiotic resistant bacteria issues. Read this if you've got a vacation to Southeast Asia planned because being told "avoid lemons" and "avoid cold drinks" and then being prescribed a pile of pills including antacids can be frustrating.
