Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long- term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team's findings appear in the journal Cell Metabolism, said, "I'm still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socializing, he added, "It's not just a sedentary (久坐的) lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said，"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.

During the rosy years of elementary school(小学), I enjoyed sharing my dolls and jokes, which allowed me to keep my high social status. I was the queen of the playground. Then came my tweens and teens, and mean girls and cool kids. They rose in the ranks not by being friendly but by smoking cigarettes, breaking rules and playing jokes on others, among whom I soon found myself.
Popularity is a well-explored subject in social psychology. Mitch Prinstein, a professor of clinical psychology sorts the popular into two categories: the likable and the status seekers. The likables’ plays-well-with-others qualities strengthen schoolyard friendships, jump-start interpersonal skills and, when tapped early, are employed ever after in life and work. Then there’s the kind of popularity that appears in adolescence: status born of power and even dishonorable behavior.
Enviable as the cool kids may have seemed, Dr. Prinstein’s studies show unpleasant consequences. Those who were highest in status in high school, as well as those least liked in elementary school, are “most likely to engage(从事) in dangerous and risky behavior.”
In one study, Dr. Prinstein examined the two types of popularity in 235 adolescents, scoring the least liked, the most liked and the highest in status based on student surveys(调查研究). “We found that the least well-liked teens had become more aggressive over time toward their classmates. But so had those who were high in status. It clearly showed that while likability can lead to healthy adjustment, high status has just the opposite effect on us.”
Dr. Prinstein has also found that the qualities that made the neighbors want you on a play date—sharing, kindness, openness—carry over to later years and make you better able to relate and connect with others.
In analyzing his and other research, Dr. Prinstein came to another conclusion: Not only is likability related to positive life outcomes, but it is also responsible for those outcomes, too. “Being liked creates opportunities for learning and for new kinds of life experiences that help somebody gain an advantage, ” he said.

The Financial Times gave part of my job to a robot named Amy last week. For years I have been making podcast version(播客)of my column, but now I am faced with a tough competition.
To be fair, Amy1.(do) something going for her. She has a great voice, smooth as velvet. Her2.(two) advantage is that she's practically free. She is part of a new service from Amazon that turns text3.speech, costing-nearly nothing. Even more4.(impress) is her speed. Less than two seconds after receiving my5.(write) text, which means when I just start to read, "Yesterday the Finan…", she has already finished.
Yet once I got over my distress and listened to her work, I felt6.(good). I know it's early days for her, but at the moment Amy is no match for me. Listening to her is not like listening to7.non-English speaker read aloud, but to someone without brain, or heart, or sense of humor. Her8.(deliver) is so poor that I don't even understand. Amy never reads with understanding, never knows when9.(pause), and never does irony. She continues to get it wrong.
Finally, I'm not afraid Amy is about to steal my job. Only people possess human touch. It is the heart-to-heart communication10.makes us special, beautiful and irreplaceable.
