    According to a survey, only 4% of the people in the world are left-handed. Why? One theory centers on the two halves of the brain. For example, the left half and the right half, each of which functions differently. Medical science believes that the left half of the brain dominates over the right half. The foundation of this theory is the fact that nerves from the brain cross over at neck-level to the opposite side of the body, and nerves from the other side of the brain reciprocate (互换). The end re­sult is that the opposite sides of the body are controlled by the opposite sides of the brain.

    The dominant left half of the brain, which kindly supplies the right half of the body, theoretically makes it more skillful in read­ing, writing, speaking, and working, and makes most people right-handed. Lefties, however, whose right half of the brain dominates, work best with the left side of their bodies.

    Theory number two focuses on the asymmetrical nature of the body. Examples of the asymmetry, which flows from head to toe, are that the right side of our faces differs slightly from the left, that our legs differ in strength, or that our feet vary in size. One aspect of this asymmetry is that for most people the right hand is stronger than the left.

    There is no doubt that all exist in a “right-handed society”, which produces most basics, including scissors, doorknobs, locks, screwdrivers, automobiles, buttons on clothing, and musical instru­ments for the 96%. Left-handed people make up for the unfairness by being members of an elite (精英) society, which includes many of the greatest geniuses, including Michelangelo and Leonardo da Vinci.

    Jordan wakes at 6 a.m. She helps her disabled mother, who is recovering from surgery for breast cancer, into the bath. Jordan has it all timed. She has a quick breakfast as her mother bathes, and returns to help her out of the bathtub and into her room. Before going to school, the 14-year-old has to walk the dog. In the evening, Jordan takes care of the family's animals and helps her mother into bed. Then she had a chance to eat dinner, do homework and wind down before going to sleep. Bedtime can be past midnight for the Florida nine-grader.

    “You have to have a certain level of maturity (成熟) to do it,” She says. As a determined student, Jordan is already planning a career in medicine.

About 1.4 million children between ages 8 and 18 are caregivers nationwide, according to American Association of Caregiving Youth (AACY). Evenly divided between girls and boys, about a third are between 8 and 11, and nearly 40% are between 12 and 15. For the young caretakers, most common are chores like shopping, fixing meals and household tasks, or keeping the family member company. Hands-on care includes helping loved ones with day-to-day activities such as bathing, dressing and toileting, getting in and out of bed and chairs, and feeding.

    AACY is a nonprofit organization supporting caregiving kids in various ways, including financial assistance, caregiving education and camps to connect young caregivers to peers. Through AACY's Care Giving Youth Project, Jordan is not alone and she is able to develop friendships with teens like her. “I felt much more relieved and less embarrassed because I wasn't the only one.” She says. “I met one of my best friends and I'm still friends with her today.”

    There is light at the end of the tunnel for Jordan. “Seeing the people I'm taking care of become better gives me a relief that things will get better,” she says. She believes that AACY will continue to help her mother when it's time for her to go to college.

    On a freezing cold day, a couple had to move into a small apartment because of their failure in business. The husband worked day and night to support the family but gave no care of his wife. So she thought, "He doesn't love me any more. He just cares about his business ... not me"．

    One day, she was about to take a shower when he stopped her at the door, "Let me take it first, okay?" "Why not me first?" she asked. "I am tired, honey, you take it later, okay?" She was entirely unhappy.

    One day, she found nothing to do and turned on his computer. A few words came into her sight. Reading them, she burst into tears. It was his diary：

    Today, I was quite sad. She asked me why I was always taking the shower first, and I said to her, "I was exhausted." She was unhappy. In her mind, I treated her not as well as usual, but what could I do? I was not as rich as before! We moved to the small apartment, and there was only one shower in the bathroom. It was so cold to take a shower in such a cold winter. But I found that if one person took the shower first, the room could get a little warmer. So every day I rushed to the bathroom first. I was thinking that, when she took the shower, the room would get warmer, even if it was only 1℃.

    Now I cannot give her a comfortable life, take her to good restaurants, or buy expensive dresses for her, but at least, I can give her 1℃ love.

    Why does most of the world travel on the right side today? Theories differ but there's no doubt Napoleon was a major influence. The French have used the right since at least the late 18^th century. Some say that before the French Revolution, noblemen drove their carriages on the left, forcing the peasants to the right. Regardless of the origin, Napoleon brought right-hand traffic to the nations he conquered, including Russia, Switzerland and Germany. Hitler, in turn, ordered right-hand traffic in Czechoslovakia and Austria in the 1930s. Nations that escaped right-hand control, like Great Britain, followed their left-hand tradition.

    The U.S. has not always been a nation of right-hand drivers; earlier in its history, carriage and horse traffic travelled on the left, as it did in England. But by the late 1700s, people driving large wagons pulled by several pairs of horses began promoting a shift (改变) to the right. A driver would sit on the rear (后面的) left horse in order to wave his whip (鞭子) with his right hand; to see opposite traffic clearly, they travelled on the right.

    One of the final moves to firmly standardize traffic directions in the U.S. occurred in the 20^th century, when Henry Ford decided to mass-produce his cars with controls on the left (one reason, stated in 1908: the convenience for passengers exiting directly onto the edge, especially… if there is a lady to be considered). Once these rules were set, many countries eventually adjusted to the right-hand standard, including Canada in the 1920s, Sweden in 1967 and Burma in 1970. The U.K. and former colonies such as Australia and India are among the Western world's few remaining holdouts (坚持不变者). Several Asian nations, including Japan, use the left as well—though many places use both right-hand-drive and left-hand-drive cars.

    The traditional tent cities at festivals such as Glastonbury may never be the same again. In a victory of green business that is certain to appeal to environmentally-aware music-lovers, a design student is to receive financial support to produce eco-friendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.

    Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events each year. For his final year project at the University of the West of England, James Dunlop came up with a material that can be recycled. And to cope with the British summer, the cardboard has been made waterproof.

    Taking inspiration from a Japanese architect, who has used cardboard to make big buildings including churches, Mr. Dunlop used cardboard material for his tents, which he called Myhabs.

    The design won an award at the annual New Designers Exhibition after Mr. Dunlop graduated from his product design degree and he decided to try to turn it into a business.

    To raise money for the idea, he toured the City's private companies which fund new businesses and found a supporter in the finance group Mint. He introduced his idea to four of Mint's directors and won their support. Mint has committed around ￡500,000 to MyHab and taken a share of 30 per cent in Mr. Dunlop's business. The first Myhabs should be tested at festivals this summer, before being marketed fully next year.

    Mr. Dunlop said that the design, which accommodates two people, could have other uses, such as for disaster relief and housing for the London Olympics.

    For music events, the cardboard houses will be ordered online and put up at the sites by the Myhab team before the festival-goers arrive and removed by the company afterwards. They can be personalized and the company will offer reductions on the expense if people agree to sell exterior(外部的) advertising space.

    The biggest festivals attract tens of thousands of participants, with Glastonhury having some 150,000 each year. Altogether there are around 100 annual music festivals where people camp in the UK. The events are becoming increasingly environmentally conscious.
