Husband Worried Wife's Temper
A man goes to the doctor, worried about his wife's temper.
The doctor asks, “What’s the problem?”The man says, “Doctor, I don’t know what to do.
Every day my wife seems to lose her temper for no reason. It scares me.”
The doctor says, “I have a cure for that. When it seems that your wife 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 she either leaves the room or calms down.”
Two weeks later, the man comes back to the doctor looking fresh and reborn.
The man says, “Doctor, that was a brilliant idea! Every time my wife started losing it, I swished with water.
I swished and swished, and she 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.”

Matthias Jakob SchleidenDied 23 Jun 1881 at age 77 (born 5 Apr 1804).German botanist who first formulated the theory that plants are composed of cells. Instead of plant classification, Schleiden studied plant growth and structure under the microscope. This led to his Contributions to Phytogenesis (1838), which stated that the various structures of the plant are composed of cells or their derivatives. He thus formulated the cell theory for plants, which was later eleborated and extended to animals by the German physiologist Theodor Schwann. Schleiden recognized the significance of the cell nucleus and sensed its importance in cell division, although he thought (wrongly) that new cells were produced by budding from its surface. He was one of the first German biologists to accept Darwinism. |
