Working Title for a New Medical Paper: Know Your Local Ungulates

I don't know how we got on this topic, but amidst our morning dialogue in bed today, I brought up the old saying, "When you hear hoofbeats, think horses, not zebras." This led me to further comment that the saying doesn't apply if you're camping in a tent at the edge of the Ngorongoro crater in Tanzania, which is where we were one night when we heard a herd of zebra out having a late-night snack of grass. Wes made the point that the saying, which comes from the medical world -- i.e. don't overlook the obvious diagnosis for a far-fetched one -- also must translate when in Africa. There, you are more likely to see the less-likely (by American standards) diagnoses. Which ultimately led Wes to this epiphany: "Yep. You've got to know your local ungulates."
