Travelers Diarrhea down the toilet

My GI and I are proud to say that I have not gotten travelers diarrhea or any stomach malady for that matter in over 5 years, not even in Guatemala where you order your beans with a side of stomach parasites. Last night as I was eating a cachapa at a street kitchen I pondered this great mystery of how Ive escaped the maligned runs while other wayworn travelers with rumbling tummies are ubiquitous. I have unraveled this mystery. The trick is to avoid like a (stomach) plague the places where all the other backpackers eat. Instead, eat from street vendors where all the locals are chowing. Disregard how many blatant violations of food safety practices you observe. They are inconsequential. I´ve taken to corner food carts and steered clear of gringo haunts. Think about it, everyone has heard of travelers diarrhea but have you ever heard of locals diarrhea? Enjoy your meal.
