One of Scotland's most active centenarians ( 百岁的人), Lady Morton, drove for nearly 80 years. She loved driving and spent the war years as an ambulance driver for Bangour Hospital. Aged 100 she was still driving around Edinburgh, up to Perthshire and elsewhere — the oldest among all the drivers in Scotland. But she had her first ever accident several days after her 100th birthday — she hit a traffic island (a raised area in the middle of a road where people can wait until it is safe to cross) when she took her new car for a drive in Edinburgh.

    Lady Morton, who celebrated her 100^th birthday in July, was given a car as a present. She talked about the accident happened that night. “I wasn't going fast, but I hit a traffic island. I couldn't see it, because it had no light, which I think was unbelievable and unreasonable. But I am all right and luckily my car wasn't badly damaged.

    Although Lady Morton had the accident, she didn't plan to stop driving.“Some people are just born to drive, and I think I am one of them. I've been a good driver since the first time I got in a car, she said. “I am musical, so I listen to sound of the car to know when to change gear (档位).

    Lady Morton bought her first car in 1927. The main change she had noticed since then is the traffic. “It's appalling. However, I don't mind it, because I am experienced, but I feel very sorry for beginners,” she said.

    When I was a little girl, I remember that when my dad was repairing something, he would ask me to hold the hammer, so we would have time for a conversation with each other. I never saw my dad drinking or taking a night out. All he did after work was taking care of his family.

    I grew up and left home for college and since then, my dad had been calling me every Sunday morning. And when I bought a house several years later, my dad painted it by himself in the fierce summer heat. All he asked was to talk to him, but I was too busy in those days.

    Four years ago, my dad visited me. He spent many hours putting together a swing for my daughter. He asked me to have a talk with him, but I had to prepare for a trip that weekend.

    One Sunday morning we had a telephone talk as usual. I noticed that my dad had forgotten some things that we discussed lately. I was in a hurry, so our conversation was short. Several hours later that day I received a call. My father was in the hospital. Immediately I bought a plane ticket and on my way I was thinking about all the occasions I missed to have a talk with my dad. By the time I arrived at the hospital, my father had passed away. Now it was he who did not have time for a conversation with me. I realized how little I knew about my dad, his deepest thoughts and his dreams.

    After his death I learned much more about him and even more about myself. All he ever wanted was my time. And now he has all my attention every single day.

    More than two thirds of the world's polar bears will be wiped out by 2050, according to a shocking new study. By then, scientists say, global warming will have melted 42 percent of the Arctic sea ice. By 2100, only a very few of these important creatures will be left.

    The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne, who has been asked to put polar bears on the US endangered species list.

    Polar bears depend on floating sea ice as a platform for hunting seals, which are their main food. Without enough ice, polar bears would be forced to go onto the land, where they are poorly skilled hunters, and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.

    The team of American and Canadian scientists spent six months studying bears, on the ground, from spotter planes and in the lab, using computer models. Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all­time low.

    However, not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear­hunting trips.

    As the parent of a 7-year-old boy, sometimes I feel like "no" is my most frequently said word. But if I look honestly at the big picture of my daily vocabulary, I probably would conclude that it actually contains too much "yes". Saying yes means opening myself up to new experiences, inviting new or deeper relationships. But too much "yes" leaves any of us feeling anxious, overcommitted（过分受约束的）and powerless to set and maintain boundaries in our lives.

    This had been on my mind when The Book of No: 365 Ways to Say It and Mean It－and Stop People-Pleasing.

    Forever came across my desk. The new edition of this decade-old book by psychologist Susan Newman is a must-read book for those of us who struggle to say "no" with authenticity, confidence and kindness.

    Newman calls people who feel forced to say yes all their way through life "people-pleasers". The chief symptoms of this condition include associating helping others with your self-respect, holding expectations that you will care for others and feeling unwilling to state your own needs when a request comes your way. For people-pleasers, "yes is the path of least resistance and the way to avoid damaging your relationship with the asker," Newman writes.

    The book offers brief dialogues for hundreds of scenarios in which "no" is the right answer, for reasons ranging from time management to financial pressures to emotional boundaries. Newman considers what came about among friends, at work, within families and in parenting. Reading through the scenarios, I realized they have some things in common－things that immediately started helping me improve my "no" skills.

    Do you think this book might be helpful to you? It's OK if the answer is "no", but I do highly recommend it for your Positive Reading List shelf.

Flying High

    Barrington Irving landed his record-breaking light at age 23 and founded an educational nonprofit organization. His message for kids: "The only thing that separates you from scientists is determination, hard work and a strong liking for what you want to achieve." The secret, he believes, is having a dream in the first place.

    The moment of inspiration for Irving came at the age of 15 in his parents' bookstore. One customer, a professional pilot, asked Irving if he'd thought about becoming a pilot. "I told him I didn't think I was smart enough; but the next day he took me to the cockpit (驾驶舱) of the commercial airplane he flew and just like that I was hooked."

    To follow his dream, Irving Turned down a football scholarship to the University of Florida. He washed airplanes to earn money for a flight school and increased his flying skills by practicing at home on a $40 flight simulator (模拟) video game. Then another dream took hold: flying alone around the world. He faced more than 50 rejections for sponsorship before convincing some companies to donate aircraft components. He took off with no weather radar, no de-icing system, and just $30 in his pocket.

    After 97 days, 26 stops and dozens of thunderstorms, he touched down to a cheering crowd in Miami. "It was seeing so many young people watching and listening that pushed me into giving back with my knowledge an experience." Irving has been doing it ever since. He set up his non-profit organization, Experience Aviation (航空), aiming to increase the numbers of youth in aviation career. By bring challenging project-based learning, hands-on and other educational opportunities to school districts and local communities nationwide, the organization has excited the hearts and minds of youth. "We want to create chances for students to accomplish something amazing," he notes. Perhaps Irving's most powerful educational tool is the example his own life provides.

Brushing your teeth twice a day should keep the dentist away. But if a group of scientific researchers have their wish, it will make the rest of your body healthy too. A toothbrush that checks blood sugar and bacteria while you brush is currently in development in the USA. It is one of many gadgets (小器械) proposed by engineers and doctors at the Center for Future Health in New York.

The gadgets seem fanciful, but the basic principles are simple. The gadgets should make it easy for people to detect illness long before it strikes and so seek treatment far earlier than normal. Instead of relying on hi-tech hospitals, the emphasis (重点) is shifted to the home and easy-to-use gadgets. In the long run, the technology may even prevent illness by encouraging us to lead healthier lives.

Intelligent bandages are a good example. Powerful sensors within the bandage could quickly identify tiny amounts of bacteria in a wound and determine what medicine would work best. The cut could then be treated instantly.

The biggest development is melanoma(黑色素瘤) monitor designed to give early warnings of cancer. It could be used to take a picture of your body each week, and then compare it to previous images. If a problem is found, the system would advise you to get a check-up.

If all this sounds worrying, then help is at hand. Experts are also working on a "digital doctor", complete with a comforting bedside manner. A standard computer would be able to understand your voice and answer questions about your symptoms in plain English and in a way which could calm your nerves.

Stress is no sweat either. A portable communication aid could recognize certain phrases and tones and let you know when you are about to lose your temper. The software would also suggest ways of keeping your cool.

Researchers are still struggling, however, with making the technology cheap and simple enough for the household user. That is going to be the difficult part.
