1st year students of MBBS were attending their 1st anatomy class. They all gathered around the surgery table with a real dead body. The Professor started class by telling two important qualities as a Doctor. The 1st is that NEVER BE DISGUSTED REGARDING ANYTHING about BODY; e.g. He inserted his finger in bodys mouth and on drawing back tasted it in his own mouth. Then he said them to do the same. The students hesitated for several minutes. But; eventually everyone inserted their fingers in dead bodys mouth and then tasted it. When everyone finished; the Professor looked at them and said: The most important 2nd quality is OBSERVATION; I inserted my Middle finger but tasted the Index finger. Now learn to pay attention. Moral: Life is tough; but its a lot tougher when you are not paying attention.
