A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.

    The paper, published this March in Psychology and Aging, examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96. The surveys were conducted every year from 1993 to 2003.

    Survey respondents (受访者) were asked to estimate their present and future life satisfaction on a scale of 0 to 10, among other questions.

    The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction, while middle-aged adults (age 40 to 64) more accurately predicted how they would feel in the future. Adults of 65 and older, however, were far more likely to underestimate their future life satisfaction. Not only did they feel more satisfied than they thought they would, the older pessimists seemed to suffer a lower ratio (比率) of disability and death for the study period.

     “We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade,” wrote Frieder R. Lang, a professor at the University of Erlangen-Nuremberg.

    Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.

     “Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions (预防措施),” the authors wrote.

    Surprisingly, compared with those in poor health or who had low incomes, respondents who enjoyed good health or income were associated with expecting a greater decline. Also, the researchers said that higher income was related to a greater risk of disability.

    The authors of the study noted that there were limitations to their conclusions. Illness, medical treatment and personal loss could also have driven health outcomes.

    However, the researchers said a pattern was clear. “We found that from early to late adulthood, individuals adapt their expectations of future life satisfaction from optimistic, to accurate, to pessimistic,” the authors concluded.

    There is no question that fewer teenagers are on the roads in the US.

    In 1978, 50% of 16-year-olds had got their first driving licences. In 2008, according to the US Transportation Department, it was just 30%. The number of those aged 19 and under with driving licences has also been declining since 1978, when 11,989,000 had licences. In 2010, it was 9, 932,441, or 4.1% of American drivers.

    In the UK, 683,273 teenagers have driving licences—just 1.85% of total licence holders, according to Department of Transport figures from September 2010.

    But the decline in the US may have more to do with tougher tests and the introduction of the new rule in many states, which force drivers aged under 16 to be with licensed drivers of 21 years and older when driving.

    In recent years, the annual number of journeys being made by American drivers of all ages has declined clearly for the first time ever. Car use began falling in 2007, when average petrol prices almost doubled to $ 4.12 a gallon, and the economy became worse.

    But there are signs that it is getting back to normal and America remains a country on wheels. It has a higher number of cars per head of population than any other country in the world.

    “Cars will always be a popular means of transportation in America. You have to take into consideration some places don't have access to public transportation. Cars are the only way some people can get around,” says Kristin Nevels. This makes driving necessary in some rural states, where about twice as many teenagers are on the road than in big cities.

    There exist cruel wars, fighting and sadness in the world today, so it's not only necessary, but also essential to have a good sense of humor just to help us go through difficult times in our lives. Putting a smile on someone's face when you know they are feeling depressed, as the saying goes, makes me feel good and warms my heart.

    How would you feel if you could not joke around with wife, husband, child, co-worker, neighbor, close friend, or even just someone that you are standing in line with at your corner store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with. My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine. This not only relieves stress in any situation, but also is a common manner to speak to others that are around you.

    I know of a few people that don't have a funny bone in their bodies, as they say. Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the slightest smile on their faces. They don't get the joke that makes others laugh. I am, laughing hard while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke?

    Laughing is essential to keep your stress levels under control. Without humor, we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness and bring a little light into our lives. Therefore, I believe our best medicine is to get together and tell some jokes and have some fun laughing together.

In Hollywood, few actors have experienced a career as diverse and prolific as Harrison Ford. From the fearless Indiana Jones to the charming Han Sol o and the world-weary Rick Deckard, Ford's portrayal（饰演） of iconic characters has left a permanent mark on cinema and pop culture. Yet, the irony lies in how many of his career-defining roles fell into this "late bloomer's" lap by chance.

Born in Chicago, Harrison was discouraged from pursuing a career on the silver screen early on, having failed to land any significant parts. Instead, he turned to professional carpentry（木工） as a means to keep his family fed.

But fate had other plans. While working as a carpenter in Hollywood, Ford crossed paths with numerous celebrity clients such as Joan Didion and, most notably, director George Lucas, who hired him to build cabinets for his office. Little did Ford know that this chance encounter would lead to his breakthrough role as the charming Han Solo in Star Wars. Lucas was impressed by Ford's presence and offered him the iconic role. In time, Ford rose to a star.

Ford's next lucky moment came when he tried out for the role of Indiana Jones in a massive project by Lucas and Steven Spielberg, Raiders of the Lost Ark. Spielberg initially wanted Ford for the role, but Lucas was hesitant as he had already worked with Ford on Star War and 1973'sAmerican Graffiti. Then the production team tried many other possibilities but without luck. Eventually, the role went to Ford, strengthening his status as a Hollywood legend.

The film series became a worldwide sensation, stimulating people's imagination and inspiring a generation of future archaeologists. Over 40 years and four films later, Ford found himself completing the series with the fifth and final installment. Eighty-one-year-old Harrison received a five-minute standing ovation（鼓掌） at the Cannes Film Festival Premiere and picked up an honorary Palmed' Or for his achievements.

Ford's commitment to his career is evident as he said, "I love the work! My luck has been to work with incredibly talented people, to find my way into this crowd of geniuses." Despite his legendary status in Hollywood, Ford's humility shines through.

With such a strong artistic heritage, it's no surprise that England knocks it out of the park when it comes to world-class art galleries. These are the galleries you need to add to your must-visit list.

Sainsbury Centre for Visual Arts, Norwich

Sitting on the edge of the University of East Anglia's campus, the Sainsbury Centre holds a collection of remarkable works of art spanning over 2,000 years. Inside the seminal Norman Foster building, you'll find artworks from around the world, including some stunning pieces of European modern art by Degas, Francis Bacon, and Alberto Giacometti.

Yorkshire Sculpture Park, West Yorkshire

Tearing up the rulebook when it comes to how we traditionally view art, the Yorkshire Sculpture Park strives to break down barriers by showing works from British and international artists in the open air. Set in hundreds of acres of West Yorkshire parkland, you'll see sculptures by some of the leading artists of the 20th century.

Whitworth, Manchester

After a sky-high £15 million development, the Whitworth is becoming one of the premier galleries in the north of England. Making full use of its picturesque park setting, the gallery has a beautiful art garden and a sculpture terrace (露台), all waiting to be explored. Inside the gallery, you can view an exciting programme of ever-changing exhibitions.
