The Healthy Habits Survey(调查)shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    1). How many times did you brush your teeth yesterday?

    Finding：A full 33% of seniors brush their teeth only once a day.

    Step：Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

    2). How many times did you wash your hands or bathe yesterday?

    Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day-half of the number doctors recommend.

    Step：We touch our faces around 3,000 times a day-often inviting germs(病菌)to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

    3). How often do you think about fighting germs?

    Finding：Seniors are not fighting germs as well as they should.

    Step：Be aware of germs. Do you know it is not your toilet but your kitchen sponge(海绵)that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

    Bad news sells.If it bleeds,it leads.No news is good news,and good news is no news.Those are "the classic rules for the evening broadcasts and the morning papers.But now that information is being spread amt monitored（监控）in different ways,researchers are discovering new rules.By tracking people's e-mails and online posts,scientists have found that good news can spread faster and farther than disasters and sob stories.

    "The ‘if it bleeds 'rule works for mass media,"says Jonah Berger,a scholar at the University of Pennsylvania. "They want your eyeballs and don't care how you're feeling.But when you share a story with your friends,you care a lot more how they react.You don't want them to think of you as a Debbie Downer."

    Researchers analyzing word-of-mouth communication—e-mails,Web posts and reviews,face-to-face conversations—found that it tended to be more positive than negative,but that didn't necessarily mean people preferred positive news.Was positive news shared more often simply because people experienced more good things than bad things?To test for that possibility,Dr.Berger looked at how people spread a particular set of news stories: thousands of articles on The New York Times' website.He and a Penn colleague analyzed the "most e-mailed" list for six months.One of his first findings was that articles in the science section were much more likely to make the list than non-science articles.He found that science amazed Times' readers and made them want to share this positive feeling with others.

    Readers also tended to share articles that were exciting or funny,or that inspired negative feelings like anger or anxiety,but not articles that left them merely sad.They needed to be aroused（激发）one way or the other,and they preferred good news to bad.The more positive an article,the more likely it was to be shared as Dr.Berger explains in his new book,"Contagious: Why Things Catch On."

    I remember that it was a fall morning when the orchestra teachers came into Miss Newell's third-grade classroom. “You have hands for the viola (中提琴),” Miss Ciano told me. I was excited because my hands were finally good for something. I told my parents I wanted to play, and naturally, they agreed.

    Since I first touched the viola, I haven't been able to put it down. Ignoring the difficulty, I am pulled closer to it each day.

    Classical music is truly my best friend. It is the trusted friend of every man, woman and child. Various feelings are expressed in classical music. I discovered that when I was eleven and played a Bach cello concerto (大提琴协奏曲) in a competition, the first movement was joyful, but the second movement was mysterious and full of pain. From that piece, I learned that music expressed not only feelings, but also sudden mood changes. By listening to classical music, I know that someone else share these feelings. Since I am lucky enough to be able to play classical music, I am comforted when I am upset. It gives me a way to escape from my problems for a short period. Classical music can express my joy, sadness and anger.

    Now look at that fall day and think how gullible I was for believing that anyone, even music teachers, could tell if hands were perfect for a certain instrument. I'm certain they told me I had “viola hands” not because they were fortune-teller, but because there was a lack of violists in our district. Classical music is one of the best things that ever happened to mankind. If you get introduced to it in the right way, it will become your friend for life.

    Looking out the window of his truck, Bob Fitzgerald sees large, undesirable plants growing in the fields. Visitors to his neighborhood around the Chesapeake Bay mainly see dying forests and empty farmland. Fitzgerald says the land has been in his family since the 17th century, and it has been sinking for hundreds of years. As sea levels rise salt water is entering rivers and other waterways. As a result, the ground is becoming too salty for crops to grow.

    Around the world, scientists warn that coastal (沿海 ) farms are under threat from rising seas and salt water. A World Bank report predicts that rice production in coastal areas may fall by 15 percent by the year 2050. Another study found that hundreds of millions of people will be forced to move inland because of rising waters.

    Kate Tully, an agroecologist(农业生态学家) wants to keep coastal farmers in business as the seas rise. The United States Department of Agriculture gave Tully and other researchers $ 1.1 million to study the problem. She and her team hope to give farmers ways to stay on their land. She told media that they are testing different crops on pieces of land around the coastal areas.

    "Sorghum is my new favorite crop because it can grow without rain and it can grow with lots of rain. So this is actually a pretty good option." The grain crop may be a good choice to feed the nearly 600 million chickens raised in the area each year. As farmers know, chickens can deal with salt, dry weather conditions and heavy rains. Tally's group is also testing other kinds of grain and a few crops that they believe can grow in the salt.

    Yet just being able to grow a crop is not enough. The crop has to be profitable. So an economist on the team will be looking at the numbers. But continuing to farm the land may not be the best plan of action. Some people believe the land should he given back to nature. They say the fields should be turned into wetlands, which are popular with duck hunters. "There's money in duck hunting," fully said. Hunting organizations will pay farmers for a permit to hunt on their land. Farmers could earn a lot of money from duck hunters, she said.

    Tully and her team are just getting started. It will be a few years before they really understand how to save the farms.

    Five-year-old Prisilla Perez, a student at Meador Elementary School in Willis, was unhappy with her recent haircut, which resulted from a severe disease. When students in her class started calling Prisilla a boy, she felt ashamed, often crying and losing focus in school.

    Her teacher, Shannon Grimm, sympathized with her unhappiness. Grimm and Prisilla's mom were concerned, but their ideas didn't work. “We had classroom discussions about how girls have short hair and boys have long hair, and I showed them photos of movie stars with different looks,” Grimm said. “However, it wasn't sinking in.”

Grimm thought about Prisilla throughout winter break, and one morning, she had an idea: Cut off her hair — a scary thought for Grimm, who wore her hair long and took pride in it. “I've never had short hair, and I stressed about it for two weeks before making a decision,” she said. On Jan. 4, Grimm invited a hairstylist friend to her home. “I told him to keep going, even if I cried,” she said.

    The class loved their teacher's new do, especially Prisilla, who excitedly ran off the school bus that afternoon yelling, “Mom, Ms. Grimm cut her hair!” The teacher also bought matching bows for herself and the girl, so they could style their hair together.

    In February, the teacher recommended Prisilla for the school district's Student of the Month Award, but during the Monday ceremony, she received a surprise “hero medal” from the girl. “Now we have matching awards,” says Grimm.

Prisilla's mother, Maria, said that Grimm's thoughtfulness brought her to tears. “I was shocked. I was crying. I couldn't believe it — she did something I wouldn't have the bravery to do. I will never forget that.”

    Feeding a crowd of hundreds doesn't make Kenny Seals-Nutt nervous.

    In fact, he loves being in the kitchen.

    By the time Kenny, 16, reached his third year of high school in Charlotte, US, he had become vice president of his school's cooking club.

    Kenny said he developed his love of cooking by watching his grandmother, who owned a business.

    And at the age of 5, he cooked his first dish. Taking it to school for lunch, he warmed it up in the school's microwave, while the other kids ate their sandwiches.

    "I love to eat, and it started to become more fun to cook than to have food prepared for me," he said.

    Cooking came easy to Kenny, and he enjoyed adding new ingredients (原料) into common dishes. "It started with a passion (热情) and I wanted to know more," he said.

    Last summer, Kenny put his skills to the test by working with his grandmother to cater his uncle's wedding. Kenny added new changes to the traditional (传统的) dishes that his grandma had prepared.

    Chef Frederick Mookie Hicks, owner of a catering business, said Kenny's success comes from his ability (能力) to multitask (多任务) in the kitchen.

    "He's so enthusiastic (热情的) about cooking that he doesn't let anything stop him," Hicks said.
