9、inst infection. Doctors at Brigham and Womens Hospital in Boston, Massachusetts, did the study. The team studied a chemical found in black, green, oolong and pekoe tea. This chemical is an amino acid(氨基酸) called L-theanine. The scientists say it may increase the strength of gamma delta T cells. That

10、s the letter T, not the drink. Gamma delta T cells are part of the bodys defense. First, the researchers mixed some of these cells with antigens(抗原) found in the amino acid.

11、ed a lot of interferon(干扰素), a substance that fights infection. Cells not mixed with the antigens did not produce interferon.

He said that the study also showed that the cells were able to remember the bacteria and fi

14、ght them again next time. Earlier research has already found that tea can help prevent heart disease and cancer. Doctor Bukowski says the new study must be repeated by more people. “If the findings prove to be true,” he says, “then tea drinking might also help protect against bacterial infection.” H

But getting older is not bad for many people

18、.Mounting evidence suggests aging may be a key to happiness. There is conflicting research on the subject, however, and experts say it may all boil down to this: The attitude is everything. Older adults tend to be more optimistic and have a more positive outlook on life. The big question is why seni

19、ors are happier. A recent study suggests one reason: Older adults remember the past through happy memories. Aging can bring more cheer as people become more comfortable with themselves and their roles in society. The older adults said they were enjoying more time with their family, spending more tim

20、e on hobbies and having greater financial security and did not have to work. But others are doubtful about the link between happiness and growing older. “The notion that those in old age are happier is misleading,” said Richard Easterlin, a professor of economics at the University of Southern Califo

21、rnia. “It is based on comparing people of different ages who are the same in terms of income, health and family life.” Easterlin added, “When you take account of the fact that older people who have lower income than the younger are less healthy, and more likely to be living alone, then you will find

22、 it hard to accept that they are happier.” In fact, scientists have found that as people age, their health declines and social networks disappear as their friends die, which can make the elderly less happy. Even if one does give in to ages dark side, health and happiness dont always go hand-in-hand.

23、 Its all about the attitude. Research by the University of Chicagos Yang suggests that the attitude to life and happiness is partly shaped by the era in which a person was born. It turns out that individuals who adapt the best to changes also have the highest expected levels of happiness. Despite th

24、e conflicting findings about aging and happiness, the good news is that there doesnt appear to be a limit to how much happiness one can achieve in ones life. “Most people desire happiness,” Easterlin said. “To my knowledge, no one has identified a limit to attainable happiness.” 4.What does the last
