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-blood 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 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 get 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 come 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 show no love or warmth. A cold fish does not offer much of himself to anyone.

“Out in the cold” is and 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 our in the cold. And it is not a pleasant place to be.

Coffee is one of the world's most widely-enjoyed drinks. Now, a new research suggests that if you drink enough coffee, it might help you avoid certain kinds of cancer.

Dr. Mia Hashibe of the University of Utah School of Medicine was interested in the connection between coffee drinking and certain cancers of the head and neck. Researchers have looked into this before, but without reaching any firm conclusions. She said, "So this finding from our new study was quite a surprise. We didn't really have any expectation of which direction it could go into."

To sort out the confusion, Hashibe and her assistants used statistical (统计学 ) techniques to, in effect, make one big study out of the earlier smaller studies. She explained,  "Thanks to the earlier studies, we have a lot more power than earlier studies that looked at this. And we included 4,000 cancer patients who have cancer of the mouth and throat. And then 9,000 controls, people who do not have cancer. '

Those studies--in Europe and the United States--found that people who drank a lot of coffee were less likely to develop cancers of the mouth and throat. "We saw a protective effect for drinking more than 4 cups of coffee per day," Hashibe said. "This was the 40 percent decrease in risk. We did not see the same effect for drinking three cups or less per day."

Mia Hashibe said there was a weak connection between cancer risk and drinking coffee without caffeine. And she and her assistants found no proof that drinking tea provided the same protection as drinking Coffee. Their research is published in the journal Cancer Epidemiology, Biomarkers & Prevention.

Hashibe says it is not clear how coffee might protect drinkers from certain cancers. "There are a few chemicals that are known to be antioxidants （抗氧化物）in coffee. So we are thinking perhaps they are playing some sort of protective role against several cancers."
