    You may have heard adults say they are uncomfortable in the morning without a cup of coffee. One reason they may feel that way is that coffee contains caffeine(咖啡因). Caffeine appears naturally in coffee, tea, and cocoa beans, which are used to make chocolate. But now food makers are adding it to many products, from potato chips to water.

    The US government is especially worried about the problem. That's why the Food and Drug Administration (FDA) is studying the health effects of caffeine on young people. Studies show that too much caffeine can make people nervous and unable to sleep. What's more, caffeine is habit-forming. Those who consume it regularly and stop suddenly may experience headaches and feel tired.

    One of the biggest concerns is the large amount of caffeine added to so-called energy drinks, like Red Bull. A 12-ounce can of cola has about 35 milligrams of caffeine. A similar serving of Red Bull contains more than three times that amount.

    The Institute of Medicine is also working on caffeine-safety measures. “Teenagers should not drink beverages that contain caffeine. They should be aware of caffeine's effects on health and on how the brain works. Take, for example, teenagers who consume caffeine to stay awake and study for a test. They will remember less of what they just studied,” said Stallings, a member of the institute.

    Companies that make products with added caffeine claim they do not advertise them to kids. However, there is no law to stop children from buying them. So the FDA needs to set limits on caffeine, especially in energy drinks. As for added caffeine in foods, the government should just say no. If not, the amount of caffeine should be printed on food labels to remind consumers. The government must do that.

    Doctors say kids should avoid caffeine. If you need extra energy, try these natural boosters: eat right, exercise, and get plenty of sleep.

    Do you sometimes argue about what seems to you to be a simple fact? Do you argue whether it's cold outdoors or whether the car in front of you is going faster than the speed limit (限速)?

    If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who felt the elephant's trunk (象鼻) said it was like a snake. The second who felt the elephant's side said it was like a wall, while the third said it was like a spear( 矛 ) as he touched the animal's tusk. The fourth, who took hold of the elephant's tail insisted that it was like a rope. The fifth man said it looked liked a tree as he put his arms around one of the elephant's legs. The last, who was tall and got hold of the elephant's ears, said it was like a huge fan.

    Each man's idea of the animal came from his own experience. So if someone disagrees with you about a “simple fact”, it's often because his experience in the matter is different from yours.

    To see how hard it is for even one person to make up his mind about a “simple fact”, try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm water (温水)in the third. Now put your left hand in the hot water. Put your right hand in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it is hot.

    Bad news sells. If it bleeds, it leads. No news is good news, and good news is no news. Those are the classic rules for the evening broadcasts and the morning papers. But now that information is being spread and monitored(监控) in different ways, researchers are discovering new rules. By tracking people's e-mails and online posts, scientists have found that good news can spread faster and farther than disasters and sob stories.

    “The 'if it bleeds' rule works for mass media,” says Jonah Berger, a scholar at the University of Pennsylvania. “They want your eyeballs and don't care how you're feeling. But when you share a story with your friends, you care a lot more how they react. You don't want them to think of you as a Debbie Downer.”

    Researchers analyzing word-of-mouth communication—e-mails, Web posts and reviews, face-to-face conversations—found that it tended to be more positive than negative, but that didn't necessarily mean people preferred positive news. Was positive news shared more often simply because people experienced more good things than bad things? To test for that possibility, Dr. Berger looked at how people spread a particular set of news stories: thousands of articles on The New York Times' website. He and a Penn colleague analyzed the “most e-mailed” list for six months. One of his first findings was that articles in the science section were much more likely to make the list than non-science articles. He found that science amazed Times' readers and made them want to share this positive feeling with others.

    Readers also tended to share articles that were exciting or funny, or that inspired negative feelings like anger or anxiety, but not articles that left them merely sad. They needed to be aroused(激发) one way or the other, and they preferred good news to bad. The more positive an article, the more likely it was to be shared, as Dr. Berger explains in his new book, “Contagious: Why Things Catch On.”

    Aging brings wrinkles, sagging bodies and frustrating forgetfulness. But getting older is not all bad for many people. Mounting evidence suggests aging may be a key to happiness. There is conflicting research on the subject, however, and experts say it may all boil down to this: Attitude is everything.

    Older adults tend to be more optimistic and have a more positive outlook on life than their younger and stressed opposites. The big question is why seniors are happier. A recent study suggests one reason: Older adults remember the past through happy memories. Aging can bring more cheer as people become more comfortable with themselves and their roles in society. The older adults said they were enjoying more time with their family, spending more time on hobbies and having greater financial security and did not have to work.

    But others are doubtful about the link between happiness and growing older.

    "The notion that those in old age are happiest is misleading," said Richard Easterlin, a professor of economics at the University of Southern California. "It is based on comparing people of different ages who are the same in terms of income, health, family life." Easterlin added, "When you take account of the fact that older people have lower income than younger, are less healthy, and more likely to be living alone, then you will find it hard to accept that they are happier.

    In fact, scientists have found that as people age, their health declines and social networks disappear as their friends die, which can make the elderly less happy.

    Even if one does give in to age's dark side, health and happiness don't always go hand-in-hand. It's all about attitude. Research by the University of Chicago's Yang suggests that attitude about life and happiness, is partly shaped by the era in which a person was born. It turns out that individuals who adapt the best to changes also have the highest expected levels of happiness.

 Despite the conflicting findings about aging and happiness, the good news is that there doesn't appear to be a limit to how much happiness one can achieve in one's life. “Most people desire happiness,” Easterlin said. “To my knowledge, no one has identified a limit to attainable happiness.”

    It was Saturday morning. I heard loud noises of moving furniture in the next room. I could almost feel the excitement of John who was soon going to get a room of his own. I remember my own feelings when I was 13. I knew how much he longed for his right to privacy (私人空间) when he was sharing a room with his younger brother, Robot. He said, “Mum, Can I please have a room of my own? I could use Jeff's. He won't mind.”

    It was true that Jeff had graduated from college and flown from the nest. But would he mind? The room was the place where I told him a thousand stories and we had a thousand talks. As close as we were, though, the time came when Jeff needed a door between us. His life was spreading into areas that had less to do with family. I no longer could-or should-know everything about him.

It turned out that getting Jeff's permission was easy. He said, “Of course, Mum, it would be selfish of me to hold on to it.” Then his voice softened, “Mum, I won't be living at home again—you know that.” Behind his glasses, his eyes were lit with all the love. There were no doors closed here—they had all opened up again.

    As John and I were cleaning the room, I fixed my eyes on Jeff's things around me and could almost touch the little boy who I knew was gone forever. I looked at the room and, in my heart, I let it go. To hold on would be, as Jeff said, selfish. Now it was time for John, shouldering through the door, his eyes bright with promise of independence, to disappear behind the door. It was time for letting go to happen again.

    The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on.

    As far as the Internet being a part of our lives. - Well, that train has left the station. This expression means there is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure (血压) in a young group: teenagers.

    The study results show that teens who spend at least 14 hours a week only may cause high blood pressure, which makes your heart and blood vessels (血管) work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and other diseases.

    The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 t0 17 years old, took part in it. 134 0f the teens were described as "heavy Internet users". And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first to connect heavy web use with high blood pressure.

    The lead researcher is Andrea CassidyBushrow. She said, "Using the Internet is part of our daily life, but it shouldn't ruin us." Ms. Cassidy-Bushrow adds that it is important for teens to take regular breaks from their computers or smartphones and do some kind of physical activity. She also suggests that parents shouldn't let their children use the Internet for more than two hours a day, five days a week.

    Australian electronics and homewares retailers are preparing for the invasion (涌入) of American giant Amazon, but some have decided to take the fight up to the online-based store when it comes to local shores.

    Last week, Amazon confirmed its rapid Australia expansion by announcing that it was searching for a site to build its “fulfillment center”—a large warehouse(仓库)for storing and shipping goods purchased online—but local retailer, including one of Harvey Norman's founders Gerry Harvey, have said they will make it hard for Amazon to succeed in Australia.

    Harvey Norman sells electronics, furniture and bedding—all markets in which Amazon hopes to hold a stake, but Harvey has said that he will happily go toe-to-toe with the American behemoth to hold his ground in the Australian market.

    “In America and other parts of the world, they have just demolished (彻底打败) other retailers, no question about that, and they send a lot of retailers broke,” Harvey told News Corp on Monday. “There is no question they have one ambition and like Attila the Hun, or Alexander the Great, they just want to demolish everything in front of them and then at the end of the day claim to be victorious and make their own rules. So this is a company that is extraordinary by any measure and challenges every rule that has ever been written about a business.”

    Some analysts have said that Amazon could take in as much as 3 billion U. S. dollars in sales in its first five years in Australia (around I percent of the total 225 billion U.S. dollar market), but Harvey has refuted those claims, saying that local retailers would be putting up “one hell of a fight” when Amazon launches is main retail services in Australia. “We will be over there fighting them like no American retailer has ever fought them,” he said. “Any price that they put we will beat or equal.”

    Meanwhile, Harvey's thoughts were backed up by the former CEO of supermarket chain Woolworths. Roger Corbett, who said Amazon would struggle to keep its lower wages and claims of lightning fast delivery to rural parts when it opens in Australia. “Amazon will have an impact on the market place, but they are coming into an already very competitive market,” he told News Corp.

    Social media is one of the fastest-growing industries in today's world. Your friends' lives may look more exciting than yours on Facebook, Twitter, and Instagram, but a new research shows it is because they are faking(伪造) it.

    A recent survey has found around two-thirds of people on social media post images to their personal information to make their lives seem more adventurous. And more than three quarters of those asked said they judged their peers based on what they saw on their Instagrm, Snapehat or Facebook pages.

    The British survey, by smart phone maker HTC, found that, in order to make our own pages and lives appear more exciting, six percent also said they had borrowed items to include in the images in order to pass them off as their own. More than half of those surveyed said they posted images of items and places purely to show off, causing jealousy among friends and family.

    Behavioral psychologist Hemmings said the trend was unsurprising due to the rise of social media. "We're living in a world instant communication." she said. "Fashion and style used to live and die in magazines; now people are in search of authentic, peer-to-peer recommendations as well, making social media an equal power house to magazines and newspaper."

    "With images being shared in an instant, we desire to know what our friends are wearing, or what super stars are buying, as soon as they have got them." Such is the influence of social media sites like Instagram, 76 percent of those asked also said seeing items on social influences them to buy them, with men more likely to take style advice and buy what they see.

    Americans with small families own a small car or a large one. If both parents are working, they usually have two cars. When the family is large, one of the cars is sold and they will buy a van (住房汽车).

    A small car can hold four persons and a large car can hold six persons but it is very crowded. A van hold seven persons easily, so a family with three children could ask their grandparents to go on a holiday travel. They could all travel together.

    Mr. Hagen and his wife had a third child last year. This made them sell their second car and buy a van. In the van, the sixth and seventh seat are used to put other things, for a family of five must carry many suitcases when they travel. When they arrive at their grandparents' home, the suitcases are removed from the two seats which can then carry the grandparents.

    Americans call vans motor homes. A motor home is always used for holidays. When a family are traveling to the mountains or to the seaside, they can live in their motor home for a few days or weeks. All the members of a big family can enjoy a happier life when they are traveling together. That is why motor homes have become very popular. In America there are many parks for motor homes.

    People in developed countries are increasingly suffering from illnesses resulting from overeating. While starvation and hunger are still big problems in many poor countries in the world, more than 25 percent of the population in America and other western countries are obese. This doesn't just mean you are a little bit fat. It means you are more than 20 kilos overweight.

    Dr. John Colon from Ohio State University says the problem is only going to get worse.” As more women have gone out to work, you find that parents in general have less time to spend on preparing food. That's not just cooking, but also planning what to eat, doing the shopping and buying the fresh food. Families, therefore, increasingly rely on ready-made and frozen meals, which tends to be high in fat and contain a lot of additives(materials added to food to improve its taste) and sugar. The other thing is that parents seem to feel guilty about not spending so much time with their kids, so they tend to give more quickly to children's demands for things like sweets and chocolate.”

    Ben Brown. Who is a British Member of Parliament, blames the big food companies. He wants to ban any food advertising that is aimed at children. "The problem is that these companies spend millions of pounds selling food to children. It's all crisps (薯片) in the shape of dinosaurs and chocolate in the shape of Mickey Mouse. I meanwhat's going to be more fun to an sight-year-old —an ice cream with a free toy or an apple?"

    One food company thinks it has an answer to this: it has invented cheese-flavored cabbage and chocolate-flavored carrots. It developed the "Whacky Veg" with money donated by a cancer research charity, which found that a diet containing lots of fruit and vegetables helps reduce cancer. However, today's sweet-toothed kids need to be bribed(贿赂)into a healthy diet, and will only cat their greens if they taste different.

    The new social robots, including Jibo, Cozmo, Kuri and Meccano M.A.X., bear some similarities to assistants like Apple's Siri, but these robots come with something more. They are designed to win us over not with their smarts but with their personality. They are sold as companions that do more than talk to us. Time magazine cheered for the robots that "could fundamentally reshape how we interact with machines." But is reshaping how we interact with machines a good thing, especially for children?

    Some researchers in favor of the robots don't see a problem with this. People have relationships with many kinds of things. Some say robots are just another thing with which we can have relationships. To support their argument, roboticists sometimes point to how children deal with toy dolls. Children animate (赋予…生命) dolls and turn them into imaginary friends. Jibo, in a sense, will be one more imaginary friend, and arguably a more intelligent and fun one.

    Getting attached to dolls and sociable machines is different, though. Today's robots tell children that they have emotions, friendships, even dreams to share. In reality, the whole goal of the robots is emotional trickery. For instance, Cozmo the robot needs to be fed, repaired and played with. Boris Sofman, the chief executive of Anki, the company behind Cozmo, says that the idea is to create "a deeper and deeper emotional connection ... And if you neglect him, you feel the pain of that." What is the point of this, exactly? What does it mean to feel the pain of neglecting something that feels no pain at being neglected, or to feel anger at being neglected by something that doesn't even know it is neglecting you?

    This should not be our only concern. It is troubling that these robots try to understand how children feel. Robots, however, have no emotions to share, and they cannot put themselves in our place. No matter what robotic creatures "say", they don't understand our emotional lives. They present themselves as empathy machines, but they are missing the essential equipment. They have not been born, they don't know pain, or death, or fear. Robot thinking may be thinking, but robot feeling is never feeling, and robot love is never love.

    What is also troubling is that children take robots' behavior to indicate feelings. When the robots interact with them, children take this as evidence that the robots like them, and when robots don't work when needed, children also take it personally. Their relationships with the robots affect their self-esteem (自尊). In one study, an 8-year-old boy concluded that the robot stopped talking to him because the robot liked his brothers better.

    For so long, we dreamed of artificial intelligence offering us not only simple help but conversation and care. Now that our dream is becoming real, it is time to deal with the emotional downside of living with robots that "feel".

    More and more travellers in China nowadays prefer homestays rather than traditional hotels, as they seek private living experiences. The house-sharing model was first introduced by the website Couchsurfing, com in 2003. It is still the largest website for travellers to find accommodation(住宿) without much money to spend.

    Encouraged by her great experience of homestays in France, Maggita, 30, considered short-term hire as her first choice in her future trips. She later went back to her hometown Shanghai and ran a "shared accommodation" business.

    The short-term hire idea has been a win-win business model. For travellers, they can rent a special room at a reasonable price and also enjoy a firsthand experience of the local culture, compared with traditional hotels. For owners, they can gain much with daily rental. Now Maggita has quit her last job in an IT company and become a host of some 20 homestays, which enables her to earn a monthly income of around 40,000 —50,000 yuan.

    In recent years, China has seen many homestay booking websites such as Xiaozhu and Tujia. Chen Chi, the founder and CEO of Xiaozhu, said the model is to share rooms or apartments that are not in use with people who need them. Instead of the traditional view that Chinese people feel uncomfortable living with strangers, Chen found that a large number of travellers got along well with house owners.

    However, experts have pointed out a series of problems brought about by the fashion. Lacking supervision(监管) to those accommodation sharing websites, the service quality and accommodation safety cannot be guaranteed(保障).Experts suggest that the online websites should closely work together with communities and local police stations to improve the services.

    Valentine's Day is supposed to be about love and romance. But unfortunately, it can be just the opposite. Because of that, Feb. 15th starts the busy season for divorce lawyers, as people who were unhappy with their marriages heading into the day often decide that they no longer want to be with the one they used to love.

    A study of divorce filings (档案) in New York, Illinois and California by AttorneyFee. com, a legal referral (推荐) site, found that February is the busiest month of the year for divorce filings, up about 18% from the average month. And those seeking referrals for a divorce lawyer on the site increase 38% following the holiday, with the biggest rise on the day after Valentine's.

    Another legal site, Avvo. com, reports a 40% increase in those seeking information and advice about divorce in the period right after Valentine's Day.

"There's a very large number of people who are considering the divorce all the time, deciding whether or not to file," said Richard Komaiko, a co-founder of AttorneyFee. "On Valentine's Day, this thing is carefully considered."

    Komaiko said February has factors other than the holiday that could lead to an increase in divorces. January is the busiest month of the year for bankruptcy (破产) filings, highlighting the financial problems that often divide couples. In addition, the cold weather of February can keep couples that are having trouble indoors and closer to each other, adding to problems.

    But Alton Abramowitz, president of the American Academy of Matrimonial Lawyers, believes the holiday itself often worsen the relationship for couples who are having trouble. "There's always the clients who come in a day or two after saying 'I can't believe it. I made this beautiful dinner for my husband for Valentine's Day, but he called to say he was stuck in the office and then didn't come home at all.'" Abramowitz said, "the day can create problems that lead to them finally getting caught."

    If you love eating and drinking for free and are looking to make some pocket money, there's a job in China with your name on it. A new type of online service allows people to hire others either to eat or drink their favorite treats or satisfy their appetite without the calories that usually come with it.

    Chinese media recently reported on an increasingly popular service on online platform Taobao that's as startling as it is appealing. People can now go online and hire others to consume certain foods and drinks, and ask them to provide video evidence of them eating or drinking the said treats.

    Fees usually range from two to nine yuan ($0.30 - $1.35) plus the cost of the food. It's not exactly a get-rich-quick job, but there are quite a lot of people willing to do it for the free treats alone.

    "Bubble tea drinking" is a particularly popular service, as the chewy tapioca(木薯粉) balls and popping drink is all the rage in Asia these days, but there are also ads from people willing to eat fried chicken or hot pot for anyone willing to pay for them.

    Advertised as being "fat-free" and "free of queues", those who pay for the service will receive the full experience, which includes a 360-degree video of the drink, photos, and a detailed description. Prices of the service are based on the drink's sweetness level, its price, and popularity. Some clients even require a short written review to be sure that the person they hired actually does what they are supposed to.

    Sellers explained that most customers buy their "Bubble tea drinking" service maybe because they're trying to shake off desires while they're on a diet. Drinking bubble tea by proxy may help customers avoid high blood pressure, high blood sugar, and other health problems that the sugar-laden drink may cause.

    So why would anyone pay a total stranger to enjoy a treat rather than consume it themselves? Well, apparently, the online service is so cheap that some people simply do it out of boredom, while others get satisfaction from watching others indulge in their favorite treats.

    This indulging-by-proxy service(代享受服务)has received a lot of attention on social media in China, with some people describing it as the job of their dreams.

Everyone procrastinates(拖延). "It's part of the human condition, "says procrastination researcher Tim Pychyl." We want to feel good now. The way to do that is avoid the task." He admits that in the short term, procrastination is powerfully rewarding. The present self-benefits, of course, but not the future self.

His research has shown that people can procrastinate on nearly anything, even enjoyable tasks such as planning a vacation. Some people procrastinate cleaning. Some people procrastinate by cleaning. The top tasks people delay are advancing their careers, taking care of their health, and planning their finances.

One big factor for them is fear of failure, of not living up to expectations. Kelli Saginak, a 57-year-old health coach from Wisconsin, procrastinated about looking for a new job for years. That inability to take action only confirmed her belief that she would never do any better. "It's totally fear of judgment," says Saginak. "If I don't take the risk, I don't have to face the judgment. Yet it's simply me judging myself."

Some people embrace procrastination, insisting that the white-hot pressure of a last-minute completion makes his or her work better. But researchers have proved it wrong. "I did an experiment, putting procrastinators under restrictions of time. They did worse than non-procrastinators, but they thought they did better." says Joseph Ferrari, a psychology professor. "Non- Procrastinators focus on the task that needs to be done. They have a stronger personal identity and are less concerned about what psychologists call social esteem's how others like us."

Procrastination is usually not going to be good for you. Just thinking about what you haven't done may cause discomfort. So if you have been procrastinating on starting an exercise routine, just put on your walking shoes. If you've been putting off a work project, reread your boss's notes about it.

On April 12th, two African American men walked into a Starbucks in Philadelphia, and sat down to wait for their friend. Because they had not bought anything, an employee asked them to leave. When the two men refused, the employee called the police, and in minutes, they were arrested. It was not until later that day that they were let go.

The video of this incident posted on Twitter went viral. People across the US were outraged. Unfortunately, these practices are not uncommon today. This incident is just one example of implicit bias(内隐偏见), something that is a part of human nature.

Most of the time, implicit bias refers to people showing negative associations towards people of a different race. Starting from a young age, these feelings develop unconsciously and naturally, because our brain draws associations based on our background, cultural environment and personal experiences.

Implicit bias affects our everyday speech and actions and these unconscious decisions can be harmful to our society. There have been many examples of blacks unfairly killed by white officers, such as in the cases of Philando Castile and Alton Sterling, which happened only two years ago. Implicit bias affects the justice system, our medical system where studies show minorities are less likely to be taken seriously, and job placements where white males are likely to be judged as more capable compared to women and other minorities.

Starbucks CEO Kevin Johnson and the police have publicly apologized to the two men, and Starbucks will be holding an anti-bias training meeting on May 29^th. All Starbucks stores will be closed on that day. However, critics and experts have said that such training is done "for show" rather than to promote change.

To address this issue, many experts agree that what the world needs is a long-term program that targets the root cause. It also starts with promoting diversity in children from an early age when they have friends and playmates from different races and cultures.

Smile, please. You're on camera. This is not a joke. It seems that there are now more cameras than human beings in your community. I used to be annoyed when my children came into the toilet when I was using it. Now I worry about them coming in with camera phones. The last time it happened, I shouted, "I hope you're not filming this for YouTube." They replied, "Of course not, that's not so last month."

Escaping to a bar, I complained about this camera-filled world and many listeners shared their stories.

A Londoner told me about a woman in England who threw a cat in the street. When the surveillance(监视) video went public, she received so many death threats that she needed police protection. It seems that, if you cause an animal some pain, the population rises up to beat you to death.

A man from New York told a story of how a truck had knocked a tree down. A 23-year-old woman was hurt in the accident. However, a surveillance camera revealed that she had thrown herself down on purpose to get money from the driver. "You have to admit, the camera was the hero in that story," the New Yorker said.

Of course, there are disadvantages, too, the Londoner added, explaining that the UK now had about four million surveillance cameras. "I feel like cameras are looking at me all the time," he said.

However, my attitude really changed after someone suggested: "If you had a large body of filmed work, why not register(登记) as an actor?" So I phoned a friend and got to know that all film or video actors with speaking parts could earn at least $782 per day.

Woohoo! Now if you'll excuse me, I need to go and do some" stupid dad tricks" at home.

Short video applications are not only developing rapidly and successfully in China, but gaining more strength as people across various age groups and geographical locations are using them to kill time, record lives, and even make a fortune.

Douyin, the most popular short video app in the country, said on Monday that the number of daily active users on its app had risen to 400 million by January, 2020. That represented a whopping rise from the 250 million recorded during the same period a year ago. Such an achievement is successful, considering that the app first appeared in 2016.

People of almost all ages use the app, and they double as both viewers and content creators, the company said. For instance, those in their 50s were. more keen on creating dance-related videos and enjoyed watching video clips on wedding scenes. Those born in the 1980s liked recording childhood memories with phones and watching beautiful scenery while teenagers and younger customers were keen on videos about animes (日本动漫), comics (漫画) and cute pets.

As an emotional bond, Douyin saw 1.76 million new born babies, 180,000 college entrance exams, 380,000 graduations and 7.09 million shares, of weddings as users chose to record and upload videos of these important occasions in their life onto the platform.

With flowers increasing at high seed for top influencers, businesses are also sensing marketing opportunities. This year more marketing dollars will be given to short videos for better contact with customers and the creation of interesting content, according to Maggie Wang, president of data marketing technology firm AdMaster.

"For social marketing, it has become more important to create original content," she said. "It's highly likely to tum clicks into cash if the contents are to viewers' tastes."

Every year, billions of kilograms of fresh produce are wasted in the United States. The food ends up in landfills, producing harmful greenhouse gases. Meanwhile, millions of poor Americans go hungry, without access to healthy, affordable meals.

Evan Lutz is passionate about correcting that social injustice. And he combines that goal with a passion for business. "I've wanted to become a social entrepreneur, not just starting a business that made money but also starting one that gave back. I'm just an average guy with a passion towards making sure no food goes to waste and making sure no person is hungry in America and I want to do that through business. "

Lutz is CEO and founder of Hungry Harvest, a business which collects and sells "ugly" produce. These are fruit and vegetables that most food companies would throw away. "If you go to a grocery store, everything is growing the same exact way. All the stuff that doesn't grow the same way gets wasted and gets thrown out. So, we take all that stuff that normally gets thrown out because of its odd size or shape. We box it up into a variety of boxes. And then we deliver them to our customers once a week. We hire people that were living in homeless shelters. They were really looking to get a chance in life. "

In January 2016, Lutz appeared on the American business competition television show "Shark Tank". It connects investors with entrepreneurs. Lutz sought a $50,000 investment in Hungry Harvest, in exchange for a five percent stake in his company. Finally, he got even more than what he expected – $100,000 for 10 percent ownership.

"Regardless of social class, race and age, men say they hate to shop," says Zukin, City University of New York sociology professor. "Yet when you ask them deeper questions, it turns out that they like to shop. Men generally like to shop for books, music and hardware. But if you ask them about the shopping they do for books or music, they'll say, ‘Well, that's not shopping. That's research.'"

In other words, what men and women call "buying things" and how they approach that task are different.

Women will wander through several 1,000­square­metre stores in search of the perfect party dress. Men will wander through 100 Internet sites in search of the perfect digital camcorder. Women see shopping as a social event. Men see it as a special task or a game to be won.

"Men are frequently shopping to win," says Ann, a marketing professor at Loyola University of Chicago. "They want to get the best deal. They want to get the best and latest one and if they do that, it makes them happy. When women shop, they're doing it in a way that they want everybody to be very happy," says Ann. "They're kind of shopping for love."

"Teenage girls learn to shop from their mums and elder sisters, and they also learn to shop by examining articles in magazines like Seventeen," Zukin says. "And although men's magazines such as GQ and Esquire have long had shopping articles, it's TV that has the eye of young male shoppers," say Ann and Zukin.

"Television shows are used by young men in the same way Seventeen or Lucky is used by girls," says Zukin, "to help make clothing and toiletry choices."

"Of course, there are men who love to shop and are proud of it," Ann says. And that is important no matter whether you buy a car or a frying pan. All men love to buy but don't want to get cheated. Ann adds, "There actually are men who are interested, for example, in cooking or shopping or chinaware or things around the home—they become kind of girl magnets. Women like it."
