     For centuries, the body's blood has been linked closely with the emotions. People who show no

human emotions or feelings, are said to be cold-blooded killer.For example, the police are searching

for a cold-blooded killer.He seems to kill for no reason, and no emotion, as if taking someone's life as

nothing.

    Cold can affect other parts of the body.The expression "get cold feet" has nothing to do with cold or

your feet.The expression means being afraid to do something you have decided to do.For example, you

agree to be president of an organization.But then you learn that all the other officers have resigned, and

all the work of the organizations will be your responsibility.You are likely to get cold feet about being

president when you understand the situation.

     The expression "give someone the cold shoulder" 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 is a person.But it is a person who is unfriendly, unemotional and shows no love

or warmth.A cold fish does not offer much of himself to anyone.Someone who is a cold fish could be

cold-hearted.Now a cold-hearted person is someone who has no sympathy.Several popular songs in

recent years were about cold-hearted men or cold-hearted women who, without feelings, broke the

hearts of their lovers.

     "Out in the cold" 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.
