COLD (1) Cold weather has a great effect on how our minds and our bodies works. Maybe that is why there are so many expressions that use the word cold. For centuries, the body's blood has been 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 ways. They may do brutal things to others, and not by accident.    ´Ù¶ô¿ø ÊÊ 'Voice of America'¿¡¼­ ¹ßÃéÇÑ ³»¿ëÀÔ´Ï´Ù.
