An AA meeting invited a medical doctor to talk about the harm that alcohol does in the human body.
The doctor wanted to paint a very clear picture of what alcohol can do to the body so he prepared a simple experiment. He put some pure alcohol in a glass and the then took out a worm from a packet and dropped it in the alcohol.
Right there before the audience's eyes, the alcohol dissolved the worm in a few minutes. Then the doctor lifted the glass and showed it to the audience and said: "See what happens when to drink alcohol?"
Every one was shocked.... and then one guy shouted from the audience: "Yeah! when you drink alcohol, you will never have worms in your stomach"!
Moral of the story? Be careful how you interpret experimental results.
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
