be attentive...

First-year students at Texas A&M's Vet school were attending their first Anatomy class, with a real dead pig.
They all gathered around the surgery table with the body covered with aWhite sheet. The professor started the class by telling them, 'InVeterinary Medicine it is necessary to have two important qualities as a Doctor: The first is that you not be disgusted by anything involving theAnimal body'.
For an example, the Professor pulled back the sheet, Stuckhis finger in the butt of the dead pig, withdrew it and stuck hisFinger in his mouth. 'Go ahead and do the same thing,' he told his Students.
The students freaked out, hesitated for several minutes.
But eventually took turns sticking a finger in the butt of the dead pig and sucking on it.
When everyone finished, the Professor looked at them and said,
'TheSecond most important quality is observation.
I stuck in my middle Finger and sucked on my index finger.
Now learn to pay attention..
Life's Tough, but it's even tougher if you're stupid.

Nice lesson indeed, we seldom observe and always tend to follow others... which is one of the main cause for problems....
