A biology teacher wished to demonstrate to his
students the harmful effects of alcohol on living
organisms. For his experiment, he showed
them a beaker with pond water in which there
was a thriving civilization of worms. When he
added some alcohol into the beaker the worms
doubled-up and died.
"Now," he said, ” what do you learn from this?"
An eager student gave his answer.
"Well the answer is obvious," he said " if you
drink alcohol, you'll never have worms."
