I was out to lunch with colleagues from work - a wonderful Chinese restaurant we'd dined in many times in the past. Meals were served, conversations abound, then we headed back to the office to complete the day. But I never made it. I fell sick and barely made it back to my apartment before the insides of my stomach were on the outside. Thankfully, a day later I felt fine. However, I developed a terrible aversion to Chinese food - one that would take years to overcome.
