     Cold weather has a great effect, on how our minds and our bodies work. Maybe that is why there are

so many expressions that use the word "cold". For centuries, the body's blood has been linked closely with

the emotions. People who show no human emotions or feelings, for example, are said to be cold-blooded.

Cold-blooded people act in a merciless way. They may do brutal things to others, and not by accident. For

example, a newspaper says the police are searching for a cold-blooded killer. The killer murdered someone,

not in self-defense. He seemed to kill with no emotion.

     Cold can affect other parts of the body, the feet, for example. Heavy socks can warm your feet, if your

feet are really cold. But there is an expression-to get cold feet-that has nothing to do with cold or your feet.

The expression means being afraid to do something you had decided to do. For example, you agree to be

president of an organization. But then you learn that all the other officers have resigned. All the work of the

organization will be your responsibility. You are likely to gel cold feet about being president when you

understand the situation.

     Cold can also affect your shoulder. You "give someone the cold shoulder" when you refuse to speak to

them. You treat them in a distant, cold way. The expression probably comes from the physical act of turning

your back toward someone, instead of speaking to him face-to-face. You may give a cold shoulder to a friend

who has not kept a promise: he made to you. Or, to someone who has lied about you to others.

     "A cold fish" is not a fish. It if a person. But it is a person who is unfriendly, unemotional and show no

love or warmth. A cold fish does not offer much of himself to anyone.

     "Out in the cold" is an expression often heard. It means not getting something that everybody else got.

A person might say that everybody but him got a pay raise. He was left out in the cold. And it is not a

pleasant place to be.
