For most people, Christmas is a time to relax in the company of family and friends. But for Santa Claus, and the thousands of fake Santas who impersonate（模仿） him every year, the Christmas season is time to get to work.

    Although Santa Claus waits until Christmas Eve to take his famous sleigh (雪橇) ride, Santa impersonators can be found at shopping malls around America throughout the six weeks leading up to December 25. "When you see Santa talking with kids at your local mall, that's when you know Christmas really is on the way," says Mary Lewine of New York City.

    With the excitement of Christmas, people often forget about the real people behind the red robes （长袍) and white beards, but being a mall Santa. is a tough job. "There is more to it than just sitting in a chair. There is more to it than just a red suit," said Timothy Connaghan, who has worked as a Santa for.38 years. "Children can really put the wear and tear on you.”

    A recent survey showed some of the challenges that mall Santas face every year. About 90 percent of Santas claimed that children pulled their beards to see if they were real, and 60 percent said that up to ten kids cough or sneeze on them every day. Even more disturbing, one-third of the Santas admit to having children wet themselves while sitting on their laps.

    So why would anyone take this job? For Ben Brauch, a retired high school teacher who has worked as a Santa for the last six years, the answer is simple-the children. "I see maybe 12,000 kids in a six-week period.

    It's hard work, but it's worth it because you get to play with kids." In fact, Brauch loves his job so much that he keeps his white beard long all year.

    The World Health Organization says the widespread use of sugar in food products and drinks is a major concern in many areas. So WHO officials are calling on governments to require taxes on sugary drinks in an effort to limit their usage and popularity. The officials believe the taxes also would reduce the risk of health problems resulting from obesity.

    Obesity is a condition in which the body stores large, unhealthy amounts of fat. Obese individuals are considered overweight. A new report says that in 2014 more than one-third of the adults in the world were overweight, and 500 million were considered obese. The United Nations agency estimates that in 2015, 42 million children under age 5 were either overweight or obese. It says that number represents an increase of about 11 million during the past 15 years. Almost half of these boys and girls live in Asia and one-fourth in Africa.

    The U.N. agency blames unhealthy diets for a rise in diabetes cases. There are 422 million cases of the disease worldwide. WHO says 1.5 million people die from it every year. It says the use of sugar in food products, like sugary drinks, is a major reason for the increase in rates of obesity and diabetes.

    Temo Waqanivalu is with the agency's Department for the Prevention on Non-Communicable Diseases. He told VOA hat taxing sugary drinks would reduce consumption and save lives. Waganivalu noted that Mexico enacted a 10 percent tax on sugary drinks in 2014. He said by the end of the year, there was a 6 percent drop in the consumption of such drinks. Among poor people, the number of people who consumed sugary drinks dropped by 17 percent.

    The WHO says people should limit the amount of sugar they consume. It says they should keep their sugar intake to below 10 percent of their total energy needs, and reduce it to less than 5 percent for improved health.

    I am sure we've all come across inspiring quotes（引言）that made us nod in agreement or made us think, "Wow, that's good quotes". But we end up going back to procrastinating（拖延）on whatever it was we were procrastinating on. So is it worthwhile to read these inspirational quotes? Well, that depends.

    Quotes, books, articles, audio programs… all of these things are just tools and they're only effective when you use them. I don't know about you but most quotes I read don't do anything for me. However, every now and then, I will come across one that will positively affect me in some way such as reminding me to be grateful, getting me to work out extra hard at the gym without being pressed by my wife, or never give up when things get tough.

      From my experience, reading quotes is more effective when you're actually trying to motivate yourself rather than just reading them for the sake of reading them. The second you feel the urge to take action, you'd better immediately get up off your chair and take action.

    These quotes aren't for everyone. If you have read tons of them and have never been motivated or had a positive change in the way you look at life or how you treat others, or these quotes don't help you to insist on doing something when you feel like giving up on it, then it's probably not worthwhile to read more of them. If you have done something a bunch of times and it's not giving you the results you want, don't keep doing it. Try something else.

    Now if you've found some value in reading these quotes in the past, continue to make them more effective by letting them guide your life.

    On the night of December 8, 1992, when he was standing in a parking lot talking to friends, Tracy March jumped to the top of a car, as he had done a hundred times before. This time, though, Tracy lost his balance. His head struck the ground, hard.

    All night, Cory, Tracy's mother, stood next to her son, who was lying in a hospital bed, his brown eyes fixed in a lifeless stare. She remembered that Tracy had once mentioned organ donation. Maybe I can spare another family this pain, she thought. When the time came, she and her husband Bill signed the forms permitting his organs to be donated.

    Tracy was declared dead the next day. Twenty-four hours later, in a Boston hospital, Tracy's liver was made part of my husband, David, who was suffering from a hopeless liver disease.

    Months later, we learned from the local organ bank that the donor's parents wished desperately to meet someone who had gained life through the gift from their son. A meeting was arranged by the organ bank to bring together two families linked by the most bittersweet ties imaginable.

    The meeting was risky, but worth it. We talked for 3 hours. They showed us a picture of Tracy. We learned how he had lived and died. We learned something about Bill and Cory too.

    For the Marches, seeing David and knowing he was well seemed to ease their suffering. I'll never forget seeing David's tall figure stopped over Cory, her arms around his waist, as a mother would hug a son. For a long time they held each other tight. It was hard to know if she was saying hello or good-bye. Maybe she was saying both.

    Life for almost anyone is increasingly influenced by screens. Not only are screens themselves cheap to make, but they also make things cheaper. Any place that can fit a screen in can cut costs. And any activity that can happen on a screen becomes cheaper. The physical experience of learning, living and dying is becoming smooth glass. All of this has led to a curious new reality: Human contact is becoming a luxury good (奢侈品).

    "What we are seeing now is the luxury of human engagement," Milton Pedraza, the chief of the

    Luxury Institute, said. Expected spending on experiences such as enjoyable travel and dining is outpacing spending on goods, according to his company's research, and he sees it as a direct response to the rapid increase of screens.

    Screens exposure starts young. And children who spent more than two hours a day looking at screen got lower scores on thinking and language tests, according to early results of a landmark study supported by the National Institutes of Health. The study focuses on brain development of more than 11,000 children. Most disturbingly, the study is finding that the brains of children who spend much time on screens are different. For some kids, their cerebral cortex (大脑皮层) would become thinner before expected time. In adults, one study found an association between screen time and depression.

    There is also the reality that in our culture of increasing separation, in which so many of the traditional gathering places and social structures have disappeared, screens are filling a vital gap.

    For normal people, running away from the screen becomes impossible. It's not a luxury, and it's easy to get. It is normal for more people to need the network constantly. In addition, it has become an important part of social interaction.
