The common cold is the worlds most widespread illness, which is plagues(疫病)
that flesh receives. The most widespread fallacy(谬误) of all is that colds caused by cold. They are not. They are caused by viruses(病毒) passing on
from person to person. You catch a cold by coming into contact, directly or
indirectly, with someone who already has one. If cold causes colds, it would
be reasonable to expect the Eskimos to suffer from them forever. But they do
not. And in isolated arctic regions explorers have reported being free from
colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes. During the First
World War soldiers who spent long periods in the trenches(战壕), cold and
wet, showed no increased tendency to catch colds. In the Second World War
prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营),
naked and starving, were astonished to find that they seldom had colds. At the
Common Cold Research Unit in England, volunteers took part in Experiments in
which they gave themselves to the discomforts of being cold and wet for long
stretches of time. After taking hot baths, they put on bathing suits, allowed
themselves to be with cold water, and then stood about dripping wet in drafty
room. Some wore wet socks all day while others exercised in the rain until
close to exhaustion. Not one of the volunteers came down with a cold unless a
cold virus was actually dropped in his nose. If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the
winter?Despite the most pains-taking research, no one has yet found the
answer. One explanation offered by scientists is that people tend to stay
together indoors more in cold weather than at other times, and this makes it
easier for cold viruses to be passed on. No one has yet found a cure for the
cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms(症状)。
