| After being laid off from her job, Ann Bauer struggled financially. She worked at several lower-paid jobs, relocated to a new city and even declared bankruptcy. Then in December, she finally moved back into her parents' home at age 52. "I'm back living in the bedroom that I grew up in," she said. Taking shelter with parents isn't uncommon for young people, especially when the job market is poor. But now the declining economy is forcing some children to do so later in life-even at middle age. Financial planners report receiving many calls from parents seeking advice about taking in their grown children after divorces and lay-offs. Kim Erickson, a financial planner in California, said she has never seen older children, even those at 50, depending so much on their parents as in the last six months."These are 40-and-50-year-old children of my clients that they're helping out. We have a hard time saying no as a culture to our children, and they keep asking for more," she said. Bauer's parents won't take rent money. She's trying to save several hundred dollars a month for a house while working as a meeting coordinator. Bauer would prefer to live on her own, but without her parents' help, she would "probably be renting again," she said."Buying groceries for another person isn't stretching my budget too much," said her mother, Shirley Smith, aged 80. Parents usually feel guilty if they don't offer help. But a large number of well-meaning parents must delay retirement or scale back their dreams because they have to help their children, Erickson said. And the sliding economy might threaten their jobs. "I almost have to act like a financial therapist," she said to Shirley. "Here is the line I'm drawing for you. That's fine. You can do up to this point, but at this point, now you're starting to erode (损害 ) your own wealth." |

| American and British researchers have proved that judgments based on how someone looks are important. They found that appearance tells a lot about your personality. The researchers included Laura Naumann of Sonoma State University in California, and Simine Vazire of Washington University in Saint Louis, Missouri. They were joined by Sam Gosling of the University of Texas at Austin and Peter J. Rentfrow of Britain's Cambridge University. The results of their study were published in the Personality and Social Psychology Bulletin in December, 2009. The subjects (接受实验者) were asked to judge the personality of people they had never met. The judges examined pictures of one hundred twenty-three people. The people in the photographs had been told how to stand. They looked into the cameras without showing their feelings. The same people also were photographed the way they themselves wanted to stand. Those who wanted to smile could smile. Then the judges attempted to decide what the people were like. The researchers compared the judges' opinions with the way the people who were photographed thought of themselves. Three people who knew those in the photographs well also provided information about their personality and behavior. The judges looked for ten qualities in the people in the pictures. The qualities included extroversion (having a confident character and enjoying the company of other people) and self-esteem (being satisfied with oneself). The judges also looked for signs of loneliness, conscientiousness (正义), emotional control and religious and political beliefs. The researchers said the judges could identify some personalities even when people were pictured in controlled positions. They could recognize personalities like extroversion and self-esteem. But it was hard for the judges to decide about most other personalities under the controlled conditions. When the people smiled and stood naturally, however, judging their personalities was easy. Then the judges' choices were correct for nine of the ten personalities. Researcher Laura Nauman said that we live in the world where first impressions are important. |
