Once a group of 17-year-old schoolboys decided to break the world basketball marathon record ( 马拉松记录). They wanted to play for ninety hours and add six hours to the record. Each team had nine players, with five at a time. The boys decided each person would play 21.5 hours and then rest for 2 hours. Then it started between both of the sides at 6 o'clock in the evening.

    The first night was very hard for the players. When it was their turn to rest, they were too exited(兴奋的) to fall asleep at once. After sleeping for a short time, they had to play again.

    On the second night, they fell asleep as soon as they stopped. Some of them had trouble with their feet and hands, but the only serious problem was a psychological one. Each boy was thinking: Why am I doing this? How can I play any longer?

    After the third night, the players knew they could finish the ninety hours. The basketball on the fourth night was very slow. But in the final hours, the players got better. For the last few minutes, the players looked as fresh as when they started. How happy everyone was!

    Most people know that listening to music when they are feeling down or depressed can encourage their spirits.

    However studies have also shown that music, especially certain tones can reduce stress. Music can change brainwave patterns, deepen breathing, and bring on a totally stress-free and more open mindset（心态）. Using music to relax when considering a particular problem may not only raise your mood, but also could help you reach that "a-ha"moment and find a solution.

    Music has also been shown not only to make you feel good, but also, to be a great motivator. For example, during exercise, listening to music can keep you going, or get you to exercise more by helping you to ignore negative feelings of tiredness and focus on the pleasurable feelings you get from being absorbed in the music.

    Music is mainly used to record emotion. When we listen to a piece of music we share the artist's feelings on a visceral（本来的）level. That can be sad, and who among us hasn't put on a painful love song to share in the misery after a bad break-up? On the contrary, we can share in the delight of songs of joy and happiness, or any song or piece of music that reminds us of a particular happy time in our past.

    So next time you are feeling down, put on Beethoven' s Ode to Joy, I bet you will feel a lot better about whatever it was that was bothering you!

    You may have heard adults say they are uncomfortable in the morning without a cup of coffee. One reason they may feel that way is that coffee contains caffeine(咖啡因). Caffeine appears naturally in coffee, tea, and cocoa beans, which are used to make chocolate. But now food makers are adding it to many products, from potato chips to water.

    The US government is especially worried about the problem. That's why the Food and Drug Administration (FDA) is studying the health effects of caffeine on young people. Studies show that too much caffeine can make people nervous and unable to sleep. What's more, caffeine is habit- forming. Those who consume it regularly and stop suddenly may experience headaches and feel tired.

    One of the biggest concerns is the large amount of caffeine added to so-called energy drinks, like Red Bull. A 12-ounce can of cola has about 35 milligrams of caffeine. A similar serving of Red Bull contains more than three times that amount.

    The Institute of Medicine is also working on caffeine-safety measures. "Teenagers should not drink beverages that contain caffeine. They should be aware of caffeine's effects on health and on how the brain works. Take, for example, teenagers who consume caffeine to stay awake and study for a test. They will remember less of what they just studied," said Stallings, a member of the institute.

    Companies that make products with added caffeine claim they do not advertise them to kids. However, there is no law to stop children from buying them. So the FDA needs to set limits on caffeine, especially in energy drinks. As for added caffeine in foods, the government should just say no. If not, the amount of caffeine should be printed on food labels to remind consumers. The government must do that.

    Doctors say kids should avoid caffeine. If you need extra energy, try these natural boosters: eat right, exercise, and get plenty of sleep.

    Several Jobs That Will Be Automated By Artificial Intelligence(AI) And Robots

Translator

    Image recognition software and voice recognition software are bringing some major advances to language translation. Applications like Google's Word Lens can translate words from signs and documents in real time and there are a lot of translation apps that allow you to type in a word or phrase and will translate it for you.

    Some will even speak the phrase for you and raw word-to-word translation will be fully automated soon.

    Fast food workers

    Automated ordering booths have already made their way into a few McDonald's restaurants around the world, and cooking positions could be removed next. The booths probably can't handle customer service problems well, so televideo systems could bring in an office employee to deal with complaints.

    Field technician

    New advances in the Internet of Things could make this work obsolete.

    Low-cost sensors combined with high availability cellular／satellite communications and cloud technology are being started to automate and alarm these sites, and can be checked and maintained from a desktop or mobile device.

    Sales representative

    But, e-commerce is changing how we make purchasing decisions, especially those where there isn't much differentiation among the major competitors.

    If you're selling a high-differentiation product and／or a high-price, low-volume product you have some job security, but if you're selling a high-volume, low-differentiation product, you better start polishing your resume, said Doug Camplejohn, CEO of Fliptop. “These kind of product sales are all moving online.”

    Although I had wanted to quit smoking, I never made up my mind until New Year's Day last year. I was having a terrible headache. I knew it was time to quit.

    Searching for methods to quit smoking on the Internet is like searching for weight loss tips — there are thousands of different ways that are said to be the best, but not all are right for you. One approach that did draw my interest was apps. Along with cigarettes (烟), my phone was the only other thing I couldn't leave my apartment without.

    There are hundreds of apps for quitting smoking. I downloaded an app called QuitIt because it was said to be good. It was free and didn't cost much time as some others. You input the amount of cigarettes you smoke, the cost per pack and the time you decide to quit smoking. The app does the math and then gives you information based on the information given by you. It tracks the amount of time since you decided to quit, the money you've saved, and the danger you've avoided. The app also includes a number of health goals.

    Quitting smoking was one of the hardest things I've ever had to do. Like most stories of quitting, I did get a little sick and I felt terrible, but the most difficult part was the empty feeling I was left with. Any time I felt like a cigarette, I would open the app and track the progress I had made. If I wanted to smoke while I was on the computer, I'd immediately go to stop smoking to read a success story, or to offer support to someone else having a harder time than me.

    I quit smoking 1 year 2 months and 27 days ago. I did not smoke 6,771 cigarettes and saved $4,062.84.

    Nobel prize-winners, legendary (传奇的) authors, and famous scientists — you might think all these people were born to be creative. However, that's not always the case.

    While well-known figures like Pablo Picasso and Albert Einstein did their most significant (重要的) work in their youth, famous American poet Robert Frost and English-born natural scientist Charles Darwin were known as "late bloomers" – people whose talents were not noticeable until later in life.

    This idea of "peaking" at different times inspired new research from the United States. "Many people believe that creativity is exclusively (独有地) associated (有联系的) with youth, but it really depends on what kind of creativity you're talking about," said Bruce Weinburg, a professor of economics at the University of Chicago and co-author of the study.

    According to the study, published earlier this month in the journal De Economist, there are two types of people: conceptual (概念的) and experimental thinkers.

    To reach this conclusion, researchers took the 31 previous winners of the Nobel Prize in economics and arranged them according to when they did their most significant work, to identify (识别) their creative peaks.

    Some peaked from ages 25-29. Classified as conceptual thinkers, these people think outside of the box, coming up with new ideas before they become used to the conventional way of doing things.

    The second creative peak came with economists in their 50s. These are experimental thinkers who have been in their field for a long time. This allows them to learn from errors and experiment with different processes, before eventually finding new solutions.

    "Whether you hit your creative peak early or late in your career depends on whether you have a conceptual or experimental approach," said Weinburg. He added that their study isn't limited to economics, saying it can apply to other creative disciplines (知识领域). So if you're struggling to come up with new ideas, don't panic. Your creative peak may be yet to arrive.
