CHICAGO (Reuters) - Smoking not only can wrinkle (起皱纹) the face and tarn it yellow—it can do the same to the whole body, researchers reported on Monday.

The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body—even skin protected from the sun.

"We examined non - facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr.Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.

"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers.Similar findings were seen in participants aged 45 to 65 years," Helfrich "s team added in their report.

The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged, in age from 22 to 91 and half were smokers.Independent judges decided how wrinkled each person' s skin was.

When skin is exposed to sunlight, notably the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich ' s team wrote.

Several previous studies have found that cigarette smoking contributes to premature(过早的)skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.

The report did not discuss die mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels (血管) beneath the skin to constrict (紧缩), reducing blood supply to the skin.

Smoking can also damage the connective tissue that supports both die skin and the internal organs,.

When your skin is exposed to sunlight long, it-becomes all of the following but _____.

    A.flexible     B.coarse           C.rough        D.discolored

    A.the number of cigarettes a person smokes.

    C.how long a person smokes

    A.it will lower blood supply to skin                  

    B.it can make you feel tired

    C.it can make skin come off                       

    D.it can make blood run faster

    A.inform people about the result of the study         

    B.advise people how to protect skin

    C.warn people not to smoke again                  

    D.introduce a new way of avoid skin aging

Very old people do raise moral problems for almost everyone who comes in contact with them. Their values—this can't be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms (蠕虫), and an old person lying alone in bed, taking no notice of the worms. But is it interfering (妨碍) with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old.
Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results. And at what point should you stop treating the old body? Is it morally right to try to push off death by pursuing the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You cannot ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there's life, there's hope.
When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun.

In the United States, 30 percent of the adult (成年人) population has a “weight problem”. To many people, the case is clear: we eat too much. But scientific evidence(证据)does little to support the idea. Going back to the America of 1910, we find that people were thinner than today. Yet they ate more food. In those days, people worked harder physically, walked more, used machines much less, and didn’t watch TV.
Several modern studies, moreover, have shown that fat people do not eat more on average (平均) than thinner people. In fact, some investigations (调查), such as a 1990 study of 3,545 London office workers, show that fatter people eat less than slimmer people.
Studies show that slim people are more active than fat people. A study by a research group of Stanford University School of Medicine found the following interesting facts:
The more the men ran, the more fat they lost.
The more they ran, the more they ate.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
【小题1】What kind of physical problem do many adult Americans have?

A.They are too thin.B.They work too hard.
