I got sent to the Pacific with a medical lab, and had to
learn a lot about tropical medicine in a hurry. You can't
imagine what a headache it is to get those people to pay
attention to the simple things that would keep them from
being half sick all the time from parasitic diseases. One of the Filipino doctors I knew thought it a big joke that
to get Rockefeller money for educating their kids, they'd build beautiful cement latrines. But they wouldn't use them!
