[GH85Carrera]

A woman goes to the Doctor, worried about her
husband's temper. The Doctor asks: "What's the problem?"

The woman says: "Doctor, I don't know what to do. Every day
my husband seems to lose his temper for no reason. It scares me."

The Doctor says: "I have a cure for that. When it seems that your
husband is getting angry, just take a glass of water and start
swishing it in your mouth. Just swish and swish but don't
swallow it until he either leaves the room or calms down."

Two weeks later the woman comes back to the doctor looking
fresh and reborn. The woman says: "Doctor, that was a brilliant
idea! Every time my husband started losing his temper, I swished
with water. I swished and swished, and he calmed right down!
How does a glass of water do that?"

The Doctor says: "The water itself does nothing. It's keeping
your mouth shut that does the trick."
