Owning a smartphone may not be as smart as you think. It may let you surf the Internet, listen to music and snap photos wherever you are…but it also turns you into a workaholic, it seems.

    A study suggests that, by giving you access to emails at all times, the all-singing, all-dancing mobile phone adds as much as two hours to your working day. Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles.

    The study by technology retailer Pixmania reveals the average UK working day is between 9 and 10 hours, but a further two hours is spent responding to or sending work emails, or making work calls. More than 90 percent of office workers have email-enabled phones, with a third accessing them more than 20 times a day. Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers confess(承认) they are on call almost 24 hours a day, with nine out of ten saying they make work emails and calls outside their normal working hours. The average time for first checking emails is between 6 a.m. and 7 a.m., with more than a third checking their first emails in this period, and a quarter checking them between 11 p.m. and midnight.

    Ghadi Hobeika, marketing director of Pixmania, said, “The ability to access literally millions of apps, keep in contact via social networks and take photos and video as well as text and call has made smartphones invaluable for many people. However, there are drawbacks. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people literally cannot get away from work. The more constantly in contact we become , the more is expected of us in a work capacity(容量).”

    Coca-Cola has created a publicity stunt (作秀) in Singapore — a vending machine (自动售货机) which gives out free cans of Coke in return for (作为对…回报) hugs. The whacky idea is part of the company's Open Haziness campaign (运动) designed to attract young people in Singapore.

    Students at the National University of Singapore were surprised to find that the soft drinks company had placed the machine in the schoolyard. But instead of the drinks brand's logo (标志), the words “Hug Me” are written across its red-and-white logo. Instead of paying money, customers have to hug the drinks machine to receive a free can of Coke.

    Public displays of affection are uncommon and have long been discouraged in Singapore, but are on the rise among young people. The move is part of a campaign created by advertising firm Ogilvy & Mather, intended to let the youth to see the brand as a non-threatening (无威胁的) friend.

    Leonardo O'Grady, leader of the campaign, said, “Happiness is contagious (传染的). The Coca-Cola Hug Machine is a single idea to spread some happiness. We want to spread happiness in an unexpected, creative way to attract not only the people present, but the audience at large.”

    He hopes that it will encourage consumers to bring positivity, optimism (乐观) and fun into their lives and to open a Coke, sharing a little happiness.

    The machines haw been such a success that there are plans to roll them out across Asia. Mr. O'Grady added, “The reaction was amazing — at one point we had four to five people hugging the machine at the same time as well as each other! In fact, there was a long line of people looking to give hugs.”

    My youngest son Jack has begun to learn the cello (大提琴). Every night, he carefully gets his cello out of its case and begins practising. I won't lie; It's not pretty. While he's getting better every day, he has a long way from becoming the next Yo-Yo Ma.

    This led me to wonder what Yo-Yo Ma was like the first time he played the cello. Of course, we now know him as one of the most excellent artists in the world, but I'm sure that when he first tried, he wasn't much better than my son. I'm not suggesting that Jack is going to take the classical music world by storm one day. But he's got to start somewhere.

    Michael Jordan wasn't born playing basketball, but I'm sure that he had to start somewhere. Warren Buffett wasn't born making great investment choices, but he had to start somewhere. J. K. Rowling wasn't born a writer, but he had to start somewhere. Bruce Springsteen wasn't born a songwriter and performer, but he had to start somewhere. Each of these individuals is now famous as being at the top of their occupation. But when they first started, their skills would have been disappointing and their potential unrealized. It has taken years of hard work to realize their undoubted talents. But they had to start somewhere.

    I don't know what my kids are going to do with their lives, but they have a great opportunity to explore a wide range of experiences before focusing on one or two things that they can be crazy about and good at. It's my job as dad to encourage them not to be put off by their bad first efforts. Because everyone has to start somewhere.

    Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have recorded how ants choose their next queen — the female whose job is to produce eggs.

    New technology is helping to improve researchers' understanding of the insects. But there is still a lot to be learned.

    Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide.

    David Hu is an engineer with the Georgia Institute of Technology, also known as Georgia Tech, saying, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at keeping this network. "

    David Hu and other Georgia Tech researchers wanted to study ants and the secret of their engineering. They froze ant rafts and then looked at them with the help of computed technology, or CT images. The pictures showed that larger ants serve in central positions to which smaller ants hold. The larger ants create pockets of air that keep the insects afloat.

    Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal.

    Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen.

    So many of us hold on to little resentments that may have come from an argument, a misunderstanding, or some other painful event. Stubbornly, we wait for someone else to reach out to us—believing this is the only way we can forgive or rekindle a friendship or family relationship.

    An acquaintance of mine, whose health isn't very good, recently told me that she hadn't spoken to her son in almost three years. She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first. When I suggested that she be the one to reach out, she resisted initially and said, "I can't do that. He's the one who should apologize." She was literally willing to die before reaching out to her only son. After a little gentle encouragement, however, she did decide to be the first one to reach out. To her amazement, her son was grateful for her willingness to call and offered an apology of his own. As is usually the case when someone takes the chance and reaches out, everyone wins.

    Whenever we hold on to our anger, we turn "small stuff" into really "big stuff" in our minds. We start to believe that our positions are more important than our happiness. They are not. If you want to be a more peaceful person you must understand that being right is almost never more important than allowing yourself to be happy. The way to be happy is to let go, and reach out. Let other people be right. This doesn't mean that you're wrong. Everything will be fine. You'll experience the peace of letting go, as well as the joy of letting others be right.

    You'll also notice that, as you reach out and let others be "right," they will become less defensive and more loving toward you. They might even reach back. But if for some reason they don't, that's okay too. You'll have the inner satisfaction of knowing that you have done your part to create a more loving world, and certainly you'll be more peaceful yourself.

    We often hear stories of animals rescuing people. But now someone has managed to return the favor.

    The event took place one snowy January morning Thomas Smith was walking his dog, Jack, in the park." As I was walking, I just saw Jack running onto the ice towards the ducks in the middle, and then he fell into the water and couldn't climb out, "said Smith. He realized he had no choice but to try and save his dog. "Someone else told me the lake was only one-meter deep, but it was at least twice that. I had to break my way through the 6-cm ice. Finally, I got Jack by the neck, and pulled him out. I don't think I have ever felt so cold by the time we got back to dry land. And when we got there, everyone was asking if Jack was okay no one was particularly worried, about me!"

    A neighbor, Julie Brown, saw it all happen. "The dog went onto an icy lake. All of a sudden, it started to go under. There were crowds of people around, and they were all shouting and screaming. Before I knew it, the owner Smith was in the water forcing his way through the ice. I can't begin to imagine how cold it was. Everyone was very nervous, but he was as cool as a cucumber he just crawled back out, put the dog on its lead, and went home."

    Many regard him as a hero, but Mr. Smith is quite laid-back about it. "Most dog owners are the same as me. They would do what I did without a second thought. But in the future, I'm going to make sure he's on lead near any ice ponds, Pets are members of our family. Would you do the same for them?
