Older women who regularly drink green tea may have slightly lower risks of stomach and throat cancers than women who don't, according to a Canadian study that followed thousands of Chinese women over a decade. For the study, researchers used data from a long-running health study of over 69,000 middle-aged and older Chinese women. The researchers found that those who drank green tea at least three times a week were 14 percent less likely to develop a cancer of the digestive ( ) system. More than 19,000 were considered regular green-tea drinkers, who drank it more than three times a week. Over 11 years, 1,255 women developed a digestive system cancer, In general, the risks were somewhat lower when a woman drank green tea often and for a long time. Green tea contains certain chemicals which may reduce the body-cell damage that can lead to cancer and other diseases. Women who _ a lot of green tea in the study were also younger, ate more fruits and vegetables, exercised more and had higher-income jobs. None of the women smoked or drank alcohol regularly, and the researchers also collected information on their diets, exercise habits, weight and medical history. Yet even with all these things factored in, women's tea habits remained linked to their cancer risks, they noted, even though this type of study cannot prove cause and effect. The study adds to debate over the effect of green tea on cancer risks, Past studies have so far come to conflicting findings on whether green tea drinkers really do have lower cancer risks.Nobody can say whether green tea itself is the reason, since green tea lovers are often more health-conscious in general. The study lasted for more than _ . A) three years B) five years C) eight years D) ten years

Ques: CHICAGO (Reuters) - Smoking not only can wrinkle the face and turn 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 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 the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels beneath the skin to constrict , reducing blood supply to the skin. Smoking can also damage the connective tissue that supports both the skin and the internal organs. It can be inferred from the study _ . A) smoking won't make skin protected from the sun B) smoking will do damage to skin rather than other organs C) smokers over 65 usually won't worry about their skin D) the age of smokers is not connected with the result of the test
