DONT ALWAYS TRUST YOUR TEACHERS

A lecturer at a medical school was trying to convey the importance of using the sense of taste during the process of diagnosis. To demonstrate his point he conducted a diabetes test. The lecturer asked some of his students to provide urine samples for the test. When the students brought back the flasks of their urine, the lecturer dipped a finger into a sample and then licked it, telling his students that he could determine the sugar content by the taste. He then told the students to repeat the tests themselves. Although most of them were feeling a bit ill from the suggestion, they all feared failure if they refused to go along with the request. After the students performed the test, albeit with looks of disgust on their faces, the lecturer moved on to reveal the importance of observation in diagnosis. He showed them that he had been dipping his index finger in the urine samples before licking his middle finger. At which point, several students ran to the classroom windows and were violently sick.
