How is it that siblings (兄弟姐妹) can turn out so differently? One answer is that in fact each sibling grows up in a different family. The firstborn is, for a while, an only child, and therefore has a completely different experience of the parents than those born later. The next child is, for a while, the youngest, until the situation is changed by a new arrival. The mother and father themselves are changing and growing up too. One sibling might live in a stable and close family in the first few years; another might be raised in a family crisis, with a disappointed mother or an angry father.

    Sibling competition was identified as an important shaping force as early as in 1918. But more recently, researchers have found many ways in which brothers and sisters are a lasting force in each others' lives. Dr. Annette Henderson says firstborn children pick up vocabulary more quickly than their siblings. The reason for this might be that the later children aren't getting the same one-on-one time with parents. But that doesn't mean that the younger children have problems with language development. Later-borns don't enjoy that much talking time with parents, but instead they harvest lessons from bigger brothers and sisters, learning entire phrases and getting an understanding of social concepts such as the difference between “I” and “me”.

    A Cambridge University study of 140 children found that siblings created a rich world of play that helped them grow socially. Love-hate relationships were common among the children. Even those siblings who fought the most had just as much positive communication as the other sibling pairs.

    One way children seek more attention from parents is by making themselves different from their siblings, particularly if they are close in age. Researchers have found that the first two children in a family are typically more different from each other than the second and third. Girls with brothers show their differences to a maximum degree by being more feminine than girls with sisters. A 2003 research paper studied adolescents from 185 families over two years, finding that those who changed to make themselves different from their siblings were successful in increasing the amount of warmth they gained from their parents.

    "If you want to see a thing well, reach out and touch it!"

That may seem a strange thing to say. But touching things can help you to see them better.

    Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell (辨别) the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.

    All children soon learn what "Don't touch!" means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.

    There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!

    Most museums are just for looking. But today some museums have some things to touch. Their signs say, "Do touch!" There you can feel everything on show.

    If you want to see better, reach out and touch. Then you will really see!

    Shan Tianfang, died at 83 on Sept. 11, 2018 in Beijing because of multiple organ failure. His energetic oral interpretations of classical Chinese novels and historical events pushed the ancient pingshu tradition forward into the modern age for generations of Chinese.

    Mr. Shan tried for many years to avoid becoming a performer of pingshu, the Song dynasty-era storytelling tradition. Growing up in the1950s in a family of folk art performers, he had seen struggle firsthand. It was a life of constant financial troubles and low social status. So it was with great unwillingness when, out of financial necessity, he became an apprentice(徒弟) to a family friend who was a master of pingshu. He made his first public appearance in 1956.

    In the pingshu tradition, the performer wears a traditional gown and sits behind a desk equipped with a folding fan and a wooden block. The storyteller tells a legend — typically a classical Chinese epic — from memory, using different voices and exaggerated gestures as well as adding occasional background detail and commentary.

    Mr. Shan grew to love the storytelling form, which is popular across northern China. It is a demanding profession that combines acting, oration, writing, historical research and literary criticism and requires countless hours of memorization. In teahouses around the northeastern region, he became famous for his fresh takes on the classics.

    In 1976, many Chinese were hungry for some new forms of entertainment, and it was against this background that he grasped the opportunity to record a pingshu radio broadcast. He soon discovered that performing on radio was vastly different from doing so in teahouses. There were no props(道具), no reactions from the audience to guide him — just Mr. Shan and the microphone in a recording studio. So for his first radio performance, a shortened version of the historical novel. The Romance of Sui and Tang Dynasties, Mr. Shan used the studio's three recording technicians as his audience and adjusted his performance based on their reactions.

    The performance had its first appearance in 1980 on Chinese New Year, and more than 100 million Chinese were estimated to have tuned in during the 56 hours over which it was broadcast. It was the beginning of a dramatic second act both for Mr. Shan and for pingshu in the People's Republic of China. He was soon a household name across the country.

    Over six decades, Mr. Shan recorded more than 110 stories for radio and television totaling about 12,000 episodes and lasting 6,000 hours. His best-known works include his interpretations of Chinese classics like 'White-Eyebrow Hero' and 'Sanxia Wuyi' and his dramatizations of historical figures like Zhuge Liang and Lin Zexu.

    Even today, hop into a Beijing taxi and the driver may be listening to one of Mr. Shan's recordings. "For my generation, Shan Tianfang was a master," said Zhao Fuwei, 48, a Beijing taxi driver. If back then there was such thing as a viral star, then Shan Tianfang was definitely the hottest viral star.

    "Listening to his stories has made it easier to kill time in bad traffic," Mr. Zhao added. "He was so good at making complicated historical stories simple and interesting". You feel like you could empathize with the characters in his stories, even though they lived a long time ago.

    But in recent years many of the great pingshu performers have died, and the tradition is fading. By the time Mr. Shan retired in 2007, interest in pingshu among Chinese had all but been replaced by mobile phones and gaming. Nevertheless, even after retiring, Mr. Shan worked tirelessly to promote pingshu among young Chinese, instructing apprentices and starting a school dedicated to the folk arts.

    Ever willing to adapt to new technologies, he posted a message to his Sina Weibo microblog account on Sept. 6, five days before his death. It was an announcement about a new live-streamed(直播) lecture series about pingshu.

    Knowing a little first aid could be life-saving if you see someone lying unconscious.

    Too often people don't do anything because they think they will kill the patient, but by learning simple rules you could make the difference between life and death.

    First, you need to find out if they're unconscious, asleep or drunk, by squeezing the skin between their neck and shoulder and shouting. If there is no response at all, you need to establish if they are dead or just unconscious—sometimes it's very difficult to tell the difference.

    Open the airway by placing one hand on their forehead and gently tilting the head back while lifting the chin.

    If there are no signs of life—no obvious pulse and their chest is not going up and down—call an ambulance and then start cardiopulmonary resuscitation (CPR) (心脏复苏) to maintain (获得) a flow of oxygenated blood to the brain and heart.

    Do this by pushing up and down on the centre of the chest, with your hands interlocked together, constantly until an ambulance arrives.

    Push at a rate of 100 beats a minute. You can't harm them doing this and might just save a life.

    Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.

    Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.

    Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we've had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells. The body's metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.

    The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.

    To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It's also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.

Anew study suggests that Medicare could spend billions of dollars on screening (拍片检查) smokers for lung cancer that would be better spent on helping them quit and keeping others from starting.

The new study indicated that screening more often supported smokers' beliefs that they could safely continue to smoke. Most participants remained smoking because they believed screening could catch cancer early before it would threaten their lives.

"They compared how hard it was to quit smoking with how easy it was to be screened," said Steven B. Zeliadt, the lead author of the study." They engaged in magical thinking that now there's this wonderful painless external test that can save lives."

He and seven colleagues conducted the study of 37 current smokers who were offered lung cancer screening at Department of Veteran Affairs. After being screened and told the results, they were interviewed about their smoking-related heath beliefs. For about half of those, cancer was not found." Screening lowered their motivation for quitting," the team reported in July in JAMA Internal Medicine. The participants focused only on lung cancer, ignoring other potential harm of smoking.

A national study published four years ago found that annual CT screening for lung cancer three years in a row could reduce deaths among heavy smokers by about 20 percent. In an interview, Dr. Russell P. Harris, a preventive medicine specialist at the UNC-Chapel Hill, noted that" Screening is being believed by people as an alternative to stopping smoking. But stopping smoking would have huge benefits for the individual and society." Furthermore, smoking causes many other cancers.

Dr. Harris agreed that rather than screening, money is better spent on smoking prevention. He suggested providing free stop-smoking aids, sponsoring anti-smoking advertising and raising taxes on tobacco products and the age at which people are allowed to buy them.
