    Jeanne Calment, a French woman, became a record breaker on 17 October, 1995, when at the age of 120 years and 238 days, she became the longest-lived human being on record. A Japanese man died in 1986 at the age of 120 years and 237 days.

    Jeanne Calment lives in a small old people's home in the south of France; her husband, her only child and her grandson have all died. She is nearly blind and deaf and is always in a wheelchair, but her doctor describes her as being more like a 90-year-old woman in good health than someone of 120. She still has a lively sense of humor. When asked on her 120^th birthday what she expected of the future, she replied: A very short one. She also remarked that she thought the good Lord had forgotten all about her.

         So what is the key to a long life? According to some doctors, diet, exercise and no smoking are the three important factors. Jeanne Calment has followed two of the tips. She has always eaten a healthy diet, and she used to do exercise every day until she broke her leg at the age of 115. However, until recently she drank two glasses of strong red wine a day, and she does smoke (now only a little). Besides, Jeanne Calment might have got very good genes from her parents. Her father lived to the age of 94 and her mother to 86.

    A local lawyer bought her house when she was 80 under an agreement that he would pay her some money every year until her death. It must have seemed a good move at the time, but so far the lawyer has paid her at least three times the value of the house. Every year on her birthday, Jeanne Calment sends him a card saying: Sorry, I'm still alive!

    When I spent the summer with my grandmother, she always set me down to the general store with a list. Behind the counter was a lady like no one I'd ever seen.

    “Excuse me,” I said. She looked up and said, “I'm Miss Bee.”

    “I need to get these.” I said, holding up my list. “So? Go get them. ” Miss Bee pointed to a sign. “There's no one here except you and me and I'm not your servant, so get yourself a basket from that pile.”

    I visited Miss Bee twice a week that summer. Sometimes she shortcharged me. Other times she overcharged. Going to the store was like going into battle. All summer long she found ways to trick me. No sooner had I learned how to pronounce “bicarbonate of soda” and memorized its location on the shelves than she made me hunt for it all over again. But by summer's end the shopping trip that had once taken me an hour was done in 15 minutes.

    “All right, little girl,” she said. “What did you learn this summer?” “That you're a meanie!” I replied. Miss Bee just laughed and said, “I know what you think of me. Well, I don't care! My job is to teach every child I meet life lessons. When you get older you'll be glad!” Glad I met Miss Bee? Ha! The idea was absurd…

    Until one day my daughter came to me with homework troubles. “It's too hard,” she said. “Could you finish my math problems for me?”

    “If I do it for you, how will you ever learn to do it yourself?” I said. Suddenly, I was back at that general store where I had learned the hard way to add up my bill by myself. Had I ever been overcharged since?

    Apple announced its new iPhones last week, but competitors' mobile phones can do many of the same things for less money.

    The new iPhone 8 and X have wireless charging, edge-to-edge glass screen and double cameras. But all of these features are already available in smart phones from China's Huawei and Oppo, and Korea's Samsung. While Apple asks buyers to pay $1,000 for its high-end model, some Asian phone makers can offer similar features for less.

    At one time, Chinese manufacturers copied features and designs from others to produce low-cost phones. But they have now added high-end features to their phones and they control nearly half the global mobile phone market.

    Media MarktSaturn is Europe's biggest electronics seller. A spokesperson for the store told Reuters that,“Huawei is seen as a relevant competitor to Apple and Samsung by covering all major price points and placing big investments in marketing and sales. '' She also said that the Chinese companies Huawei, ZTE, Lenovo and TCL were among the top-10 best-selling smart phones in its stores.

    Chinese manufacturers' fast growth has been fueled by strong sales in China. But they now export 40 percent of their smart phones. That is almost double the number from just three years ago, according to the Hong Kong investment company CLSA.

    Huawei is currently the world's third largest phone maker behind Samsung and Apple. According to research company Canalys, the Chinese company is getting closer to second-place Apple and might overtake it later this year.The Chinese company even made fun of Apple's new facial recognition feature with a Facebook video called "Real AI phone." Huawei plans to show its top-of-the-line Mate 10 phone on Oct. 16. The phone will have artificial intelligence features such as instant translation and image recognition and will cost less than $1,000.    Other Chinese companies are looking to enter the high-end smart phone market.

    A few years back I worked in a university building that also housed a department full of psychologists, all of whom seemed to see us as perfect guinea pigs(豚鼠) for their latest theories. If an eager graduate student showed up in my office bearing desserts and asked me to pick one, I'd cast a careful glance and ask "Why?" before grabbing the apple pie.

    So one day, when someone from the Psychology Department posted instructions in the bathroom persuading all of us to "Think about five things for which you're grateful every day for a week!" my response was frankly doubtful. I did the math. Five things a day for seven days is a lot of brainpower to expend without so much as the promise of an apple pie.

    I wandered into the office of Heidi Zetzer, the director of our school's Psychological Services Clinic. "What's with the gratitude thing?" I asked. You don't ask an academic question－even a simple one unless you're prepared for a long answer. Heidi came alive, and I sat down. That's when I first heard the term "positive psychology". The gratitude thing, as I had called it, was but one small and simple element of the practice. "Kind of like training the brain to focus on joy," my friend Heidi explained. "It's only a week," she urged. "Try it." I did. And guess what? It worked.

    Every day for a week, I found five distinct things for which I was thankful. They had to be different every day. I couldn't get away with just being grateful for my wonderful husband. But I could, suggested Collie Conoley, another positive psychologist, express my gratitude for specific aspects of a certain person each day. He's a great cook. He always puts our family first.

    Life will never be perfect. I still see new stories that annoy me. The traffic in my city is maddening. I wish I could speed up my recovery. But with just one simple exercise, I'm rediscovering the peace of that old saying: accepting the things I can't change, working without complaint to change what I can, and being wise enough to know the difference.

    And all it took was a little gratitude.

    Many automobile makers present their newest designs at car shows around the world. Many designers seek to create the car of the future. One device that is popular among car manufacturers(生产商) is an autopilot. Autopilot permits a car to drive itself without human control.

    A recent car show in Geneva, Switzerland also presented other possible designs, including cars manufactured in 3-D printers.

    Rinspeed is a Swiss design company. It showed a vehicle based on the US electric car Tesla Model S, but the Rinspeed car includes a large television and an espresso coffee maker.

    Frank Rinderknecht is the CEO of Rinspeed. He says he does not want to just sit and watch the steering wheel(方向盘) turn as he rides in a car with autopilot.

    "I want to ride; I want to sleep, relax, watch movies, news, anything else. So that's the vision which we have. One day on the boring motorway traffic, you just do anything which makes your life better," said Rinderknecht.

    One of the most interesting ideas presented at the show is a car built on a 3-D printer. The German engineering firm EDAG designed the car. The body of the vehicle called "Genesis" is printed in one piece from a material called thermoplastic(热塑性塑料).

    Christoph Horvath is spokesman for EDAG.

    "To create a car without the use of any tool. This would be a real revolution for the industry," said Horvath.

    EDAG says it based its design on a turtle shell. The company says the design provides the right amount of strength and firmness.

    Other automakers did not look so far into the future. Czech automaker Skoda presented its "Vision C" model vehicle. The car has an environmentally friendly natural gas engine.

    Jo Davidson is a company spokeswoman. She says the car releases very low levels of the pollutant gas CO₂. Ms Davidson says the "Vision C" plans to be launched in two years.

When bicycle-sharing company oBike pulled out of Singapore abruptly last year, it left the city with unattended bicycles everywhere. Myanmar businessman Mike Than Tun Win saw the perfect opportunity to turn trash (垃圾) into treasure. "What if these bicycles could be distributed to poor students in villages so they can cycle to school? " he thought.

Mr Than, 33, grew up in Mandalay, where he used to walk to school as a student. While traveling through rural (乡村的) areas in Myanmar over the last few years he saw things had not changed. Long lines of children in rural villages continue to walk 30 minutes to an hour just to get to school. "I thought if we could just reduce the time they take, they could spend more time studying, gain more knowledge and increase their chances of getting out of poverty (贫困), " he said.

With that, he started a movement called Lesswalk with the intention of buying bicycles from bike-sharing firms oBike and ofo—which have stopped operations in Singapore — and shipping them to Yangon. He would renew the bicycles before distributing them to teenagers and families living in rural villages in Myanmar, beginning with villages in Mandalay and Sagaing areas.

Over the last three months, the businessman has bought 10, 000 bicycles in Singapore and Malaysia. He paid for 5, 000 of the bicycles out of his own pocket, with other sponsors paying for the rest.

Mr Than plans to modify (修改) the bicycles so that they can better suit the needs of the children in villages. Most of the time they ride around with their little brothers and sisters. "I'm planning to add an extra seat at the back so that they can go to school together," he said. He also plans to remove the digital locks and give each a new one that works better in villages.

Including the cost of shipping, modification and distribution, Mr Than thinks each bicycle might cost him around US $35 to US $40. "I might have to spend more money, but it is better that these bicycles are going to help some people rather than going to waste," he said.
