    As traditional Chinese art, paper cutting has a long history. The first and earliest paper cutting was found in China 1,500 years ago. But this traditional art is at risk of disappearing now. Luckily, Vivian Woo, a Chinese immigrant in America, is trying to bring this art back to life.

    One Saturday in 2017，Ms. Woo held a paper cutting show at a shopping center near Washington. She got much fun and peace doing it. She hoped more people would enjoy it. Ms. Woo began to study the art of paper cutting as a 14 - year - old girl in her hometown in China. She said all the students at school had to learn paper cutting. But she had a deep love for it. So her teacher spent more time teaching her after class. Later, she won the second prize in a national painting and art competition. Ms. Woo went to America after she finished college in 2008. Soon after that, she took part in an activity to promote Chinese paper cutting. And then she was invited to show the art in many important activities. “It is important to promote this art to Americans or anyone who is interested in it. Maybe it will make this art more popular.” Woo said.

From the art of paper cutting, people can know about Chinese cultural values, history and stories of people's life. Ms. Woo uses the art as a tool to show Chinese culture to people who know little about it. Chinese art is not only for Chinese, but also for people ail over the world.

    Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.

    According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers' markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.

    After a visit to the United States, Mireille Guiliano, author of French Women Don't Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.

    In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity — or extreme overweight — among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17% — and is growing.

    Once I was troubled by tourists to do a favor for them—take their photos. Sometimes they complained that the photos I took were not good.

    Now fellow travelers trouble me in a different way—with their selfie sticks (自拍杆). I fear my head will be knocked or my eyes poked (戳) by the poles with mobile phone cameras put on them.

    Admittedly, it is a good invention. With a cool $3, you can take solo or group photos without asking for a favor from strangers. But if you want to take your selfie sticks out to travel to the West, think twice. Selfie-sticks bans have been spreading in some of the world's important museums, galleries, parks and soccer stadiums including Disney. Visitors have to leave their selfie sticks in a locker before entering to protect paintings, individual privacy and the overall visitor experience.

    In China, selfie sticks are still widely used. People would do anything to take a perfect selfie and don't pay attention to their surroundings and other travelers. Many examples have shown things could go horribly wrong when people were taking selfies. For example, earlier this year, a starfish died at the Shanghai Science and Technology Museum after a visitor took it out to take a selfie, and last year a criminal was caught by the Chinese police after the criminal posted a selfie of himself on Wudang Mountain and shared it on social media, according to the Xinhua News Agency.

    Thus, I strongly advise travelers not to take a selfie in a crowded public place, indoors or at any sensitive places such as cemeteries and memorial places, especially when the police are looking for you. If you are a die-hard selfie fan, there are some options cooler than a selfie stick. One is a waterproof (防水的) wrist-band called a “pop stick”. Just like the slap bracelets (手镯) we used to wear when we were kids, it unrolls into a stiff selfie stick. Another one is “selfie ring”, an accessory that helps you stick your phone to your hand so you can snap better selfies.

Dear Graham,

    My partner and I have recently lost a pet quite suddenly. Normal life is continuing with so much sadness for my pet meant so much to me. Lots of people won't understand my feeling this way about the death of an animal. This obviously isn't the first time someone in my life has passed away: when I was younger we lost elderly relatives who I loved very much, and naturally much-loved family pets died occasionally too. But this has hit me so much harder. I put so much love into the relationship and I'm just finding it hard to get my head around the fact that it's gone.

    Thank you for taking the time to read this.

Dear Anon,

    Something you loved deeply has gone from your life, so of course you are sad. We love our pets differently from family members or friends and part of that is because we know they will probably die before us. Our time with our dogs or cats is precious precisely because we understand it is limited.

    As humans, we go through most of life understanding we would die one day. But animals don't. We are the keeper of the secret. Of course, living a life unencumbered(不受妨碍) by thoughts of death means that our pets, in general, lead very simple, happy lives. It's one of the reasons why they are such a joy to be round. You are, of course, correct when you say that many people don't understand your grief, so don't talk to them. Share your feelings with like-minded souls. I'm sure a simple search online will reveal many practical advice for moving on.

    And when you are ready, you can welcome another animal into your life and then you will enjoy happiness again.

    A lifetime of active exercise will let you keep the body of a 20-year-old well into your 70s, scientists have found.

    The physical decline (衰退) thought to be an unavoidable part of ageing is actually the result of not exercising enough, according to the research, which found that regular cyclists kept the muscles, lungs, and even the immune system (免疫系统) of people years younger. Besides, many serious health problems could be prevented if people became more active, researchers insist.

    Janet Lord, a leading researcher, said, “Our findings prove the false belief that ageing automatically makes us weaker. We now have strong evidence that encouraging people to do regular exercise throughout their lives can solve the problem that we are living longer but not healthier.”

    She looked at 125 cyclists aged 55 to 79 who had been exercising regularly for 25 years and compared them with 75 ordinary people of a similar age and 55 people aged 20 to 36. On a series of physical measures, the cyclists showed no difference from people much younger in their immune systems and making T cells.

    Now Professor Lord aims to discover how much exercise people need to do to stay young. “You needn't work out a lot. It may be intensity (强度) that helps—like going up and down the stairs ten times a day.”

    While there is no magic method of staying mentally and physically fit in later life, the benefits of keeping active can never be ignored, whatever your age or state of health.
