First-year students at Med School were receiving their first anatomy
class,with a real dead human body. They all gathered around the surgery
table
with the body covered with a white sheet.
The professor started the class by telling them, "In medicine, it is
necessary to have 2 important qualities as a doctor:
The first is that you not be disgusted by anything involving the human
body."
For an example,the Professor pulled back the sheet, stuck his finger in
the
butt of the corpse, withdrew it and stuck it 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 body and sucking on it.
When everyone finished, the Professor looked at them and told them,
"Thesecond most important quality is observation. I stuck in my middle
 finger and sucked on my index finger. Now learn to pay attention."
