Touristas, Montezuma's Revenge, Etc UPDATED
Science News (One of my favorite magazines) reports that there is a patch now for greatly reducing your chances of getting bowel bombed on your next trip to a 2nd or 3rd world destination.
In case you need reminding about how Vengeful Montezuma can really be, read this.
If you are a subscriber to Science News, read this. (If you are not, become one. It's a great weekly that will make you scientifically literate overnight.)
Since the announcement of this marvelous breakthrough came at "at a meeting of the American Society of Tropical Medicine and Hygiene" in Philadelphia, I reckon it's not really on the market yet, but start bugging your doctor and your pharmacist for your early adopter rights.
Have a nice trip.
