Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones, substances found in cocoa, tea and some kinds of vegetables, may improve age-related memory failure.

    Dr. Scott Small is a professor of neurology (神经病学) at Columbia University in new York City. He is the lead writer of a research paper describing the effects of cocoa flavones on brain activity. His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink made from cocoa beans or a low-level flavones drink. For a period of three months, some subjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study. Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memory tests.

    The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the lead researcher of a four-year study involving 18,000 adults. This study will use flavones capsules(胶囊). The study subjects will be divided into two groups and will take two pills per day. The capsules used will all look the same. But one group's capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo

    Dr. Manson says it's not necessary for people to start eating more chocolate, because a person would have to eat a huge amount of chocolate to get the same level of flavones given to the rest subjects. He adds many manufacturers have planned to remove the flavones from their chocolate products. Similarly, Dr. Manson says a cocoa-based flavones extract(提取)may be developed in the future But he says that more studies are needed to see how much flavones is good for our health.

    In Asia, there are special competitions where kites have complex designs and are fitted with instruments that make musical sounds as the wind blows through them. Although all kites have a similar structure （结构）, they are widely different in size and shape. Kite-fighting competitions are also held, in which competitions us their kites to attack and bring down their opponents'（对手）kites or cut their strings（线）.

    For more than 15 years, the Big Wind Kite Factory has been giving kite-making and kite flying classes for the children on an island in Hawaii. In its kite-making lessons, students can make kites in as little as 20 minutes! Children as young as four years old can learn how to fly a kite. Jonathan Socher and his wife Daphne started the kite factory in 1980. Their kites are made of nylon（尼龙）.Their designs are Hawaiian themes created by Daphne. The designs are cut out of the nylon with a hot knife that seals the edges and then fastened directly onto the kite. 

    The kite that is used to give lessons is a regular diamond kite with a rainbow pattern. The difference between this kite and the ones they make during the lessons is that it is a two-string controllable kite. Big Wind employees fly the kite and for a few minutes show students how pulling on one line and then on the other controls the direction the kite goes in. Then the controls are given to the students.

    Jonathan insists that it is not necessary to make a huge impressive kite to have fun making and flying kites. Even the simplest structure can work, and can give hours of fun. Go on, give it a try!

    If you ever have the desire to break out into song—in the shower, in the car, maybe at your neighbor's karaoke night—you should embrace it whole-heartedly. This ancient art not only makes you feel good, it can also improve your well-being, reduce your feelings of pain, and even extend your life.

    Using your voice to sing, rather than simply carryout a conversation, offers unique benefits because singing affects our bodies. Also, studies link singing with a lower heart rate，decreased blood pressure and reduced stress according to Patricia Preston-Roberts, a music therapist. She uses song to help patients who suffer from a variety of problems.

    Singing, particularly in a group, seems to benefit the elderly particularly well. As part of a three-year study examining how singing affects the health of those fifty-five and older, a Senior Singers Chorus was formed by the Levine School of Music in Washington, D. C. The seniors involved in the chorus, as well as seniors in two separate arts groups about writing and painting, showed significant health improvements compared to those in the control groups (控制组).Obviously, the arts groups reported thirty fewer doctors' visits, fewer eyesight problems, less depression, and less need for medication.

    Even lead researcher Dr. Gene D. Cohen, director of the Center on Aging at George Washington University, was surprised at how big an effect the seniors' arts participation had on their health. Cohen said, “The average age of all the subjects was eighty. This is higher than life expectancy. So, if an effect were to be achieved, one would ordinarily expect to see less decline (下降) compared to the control group. The fact that there was so much improvement in many areas was the surprising factor." The seniors also noticed health improvements and they reported feeling better both in daily life and while singing.

    The part of the brain that works with speech is different from the part that processes music. “People seem to enjoy doing something jointly with other people. There are a lot of facts that being socially involved is good for people with dementia (老年痴呆).”Ballard said.

    The arts are showing up as a treatment tool in hospitals across the country. If you are thinking of volunteering, singing at a hospital may be a good choice—not only for the patients, but also for yourself.

    Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

    Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport's rules require that a race walker's knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It's this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

    Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

    However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

    As a result, she says, some of the injuries associated with running, such as runner's knee, are uncommon among race walkers. But the sport's strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
