This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.

    The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only how far and fast they run but also how well. It means the user maximizes their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes.

    Sensors (传感器) record each movement and send it by an ankle transmitter (脚踝发射器) to a smart phone. Then a “virtual coach” application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.

    The socks should be useful to athletes and weekend joggers. “People think running is so easy and of course everybody can do it but not necessarily safely and well,” Dr Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such golf, or even to help to teach women to walk better in high heels.

    Mr. Vigano said, “People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely.”

    Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around £120, which will go on sale in March.

    Many people think of guys as being carefree when it comes to their appearance. But in fact, a lot of guys spend plenty of time in front of the mirror. {#blank#}1{#/blank#}.

    Body image is a person's opinions and feelings about his or her own body and physical appearance. {#blank#}2{#/blank#}. You appreciate your body for its capabilities and accept its imperfections.

    So, what can you do to develop a positive body image? Here are some ideas:

    Recognize your strengths. Different body types are good for different things. What does your body do well? Maybe your speed, strength, or coordination makes you better than others at a certain sport. That may be basketball, table tennis, mountain biking, dancing, or even running. Or perhaps you have non-sports skills, like drawing, painting, singing, playing a musical instrument, writing, or acting. {#blank#}3{#/blank#}.

    Exercise regularly. Exercise can help you look good and feel good about yourself. Good physiques (体形) don't just happen. {#blank#}4{#/blank#}. A healthy habit can be as simple as exercising 20 minutes to one hour three days a week. Working out can also lift your spirits.

    Respect your body. Practicing good habits — regular showering; taking care of your teeth, hair, and skin; wearing clean clothes, and so on — can help you build a positive body image.

    {#blank#}5{#/blank#}. Your body is just one part of who you are. Your talent for comedy, a quick wit (智慧), and all the other things make you unique. So try not to let small imperfections take over.

A. Be yourself.

B. Just explore talents that you feel good about.

C. Use this as an opportunity to discover what you're good at.

D. They care just as much as girls do about their body image.

E. They take hard work, regular workouts, and a healthy diet.

F. The good news is that self-image and body image can be changed.

G. Having a positive body image means feeling satisfied with the way you look.

    For centuries, medical pioneers have refined a variety of methods and medicines to treat sickness, injury, and disability, enabling people to live longer and healthier lives.

    “A salamander (a small lizard-like animal) can grow back its leg. Why can't a human do the same?” asked Peruvian-born surgeon Dr. Anthony Atala in a recent interview. The question, a reference to work aiming to grow new limbs for wounded soldiers, captures the inventive spirit of regenerative medicine. This innovative field seeks to provide patients with replacement body parts.

These parts are not made of steel; they are the real things — living cells, tissue, and even organs.

    Regenerative medicine is still mostly experimental, with clinical applications limited to procedures such as growing sheets of skin on burns and wounds. One of its most significant advances took place in 1999，when a research group at North Carolina's Wake Forest Institute for Regenerative Medicine conducted a successful organ replacement with a laboratory-grown bladder. Since then, the team, led by Dr. Atala, has continued to generate a variety of other tissues and organs—from kidneys to ears.

    The field of regenerative medicine builds on work conducted in the early twentieth century with the first successful transplants of donated human soft tissue and bone. However, donor organs are not always the best option. First of all, they are in short supply, and many people die while waiting for an available organ; in the United States alone, more than 100,000 people are waiting for organ transplants. Secondly, a patient's body may ultimately reject the transplanted donor organ. An advantage of regenerative medicine is that the tissues are grown from a patient's own cells and will not be rejected by the body's immune system.

    Today, several labs are working to create bioartificial body parts. Scientists at Columbia and Yale Universities have grown a jawbone and a lung. At the University of Minnesota, Doris Taylor has created a beating bioartificial rat heart. Dr. Atala's medical team has reported long-term success with bioengineered bladders implanted into young patients with spina bifida (a birth defect that involves the incomplete development of the spinal cord). And at the University of Michigan, H. David Humes has created an artificial kidney.

    So far, the kidney procedure has only been used successfully with sheep, but there is hope that one day similar kidney will be implantable in a human patient. The continuing research of scientists such as these may eventually make donor organs unnecessary and, as a result, significantly increase individuals' chances of survival.

    People usually visit cafes to ease themselves of their tiredness and keep themselves from falling asleep, but Mr. Healing, a popular cafe chain in South Korea actually does the opposite. Customers can come in, order a drink, lie down in a comfortable massage chair, and take a nap.

    Many Koreans suffer from a lack of sleep as a result of overworking, so any opportunity to relax and even take a nap is greatly appreciated. Mr. Healing is the perfect place to go when you're on a short work or school break and you need to catch up on sleep. The cafe offers massage periods in various modes, depending on how much time you have and how you choose to spend it.

    The 20-minute session is priced at $3.5, the 30-minute massage costs $7, and the 50-minute session is $9, all of which also include a drink. Once you make your choice, you are taken to the “healing center”. You are asked to take off your shoes as well as any jewelry that might damage the chairs, after which you can choose a massage mode, from “stretch” or “sleep”. You can start with stretch for a few minutes, and then switch to sleep if you want to take a short nap. After it comes to an end, you are taken back to the cafe area to enjoy a coffee or one of the many other refreshing drinks on the menu.

    Mr. Healing cafes are so popular in Korea that customers are advised to make reservations in advance to be sure that a massage chair is available. “I have to sit on a chair and stare at a computer monitor all day due to my job, the healing room was truly effective to relieve tiredness and stress from weekdays,” said Park Hye-sun, a 24-year-old officer.

    Some have described Mr. Healing and other similar relaxation cafes in South Korea as simple fashions, but others see them as a sustainable business model, because they offer a service that Koreans really need.

    Knowing what to do at checkout and properly preparing for it can turn a potentially heated situation into a quick thank you add goodbye. Below we made a list of five things you should remember at hotel checkout.

Don't be late to check

    Hotels may add an extremely high price for being just a half hour late. If you know you won't make the cutoff time, it never hurts to call ahead and try to negotiate away a potential charge.

    Don't forget to double cheek the room and safe

    Make sure you don't leave things behind. If you have an early flight or checkout time, pack up as much as you can the night before so that last-minute rush isn't too annoying. Also, be sure to take out anything in the room safe.

    Don't forget to tip the housekeepers

    It's always polite to leave some money for the people keeping your room clean.

    Don't ignore the detailed bill

    You may be in a rush, but give the detailed hill a careful look to see if the hotel charge is different from the rate you initially booked.

    Don't get angry

    Shooting at the assistant manager standing behind the front desk probably won't help.

    When dealing with an unexpected item on the bill. Think about how difficult it can be to deal with annoyed customers. Keep calm and things may be solved better and sooner.
