The survey entitled: "No Man is an Island" showed that countries where people enjoy time with friends and family, have trust in government and national institutions were more likely to be happy than those living in a sunny climate. The study rated respondent on their overall sense of happiness and life satisfaction on a _ of one to 10. Danes --who expressed a high level of trust in their politicians and public institutions--came top of the field at 8.3. Italians--who reported lower levels of satisfaction with their national quality of government--came last at 6.49.' "Italy, Greece, Portugal, Germany and France report the lowest levels of happiness while the Scandinavian Countries, Netherlands and Luxembourg report the highest," the study said. Although Europeans are generally four times wealthier than their fathers and grandfathers, their levels of happiness are either equal to or lower than 40 years ago. The study also looked at factors contributing to happiness within countries and surprisingly found that an interest in politics actually increased happiness. Lead researcher Luisa Corrado said tax cuts and throwing money at social problems appeared to have no effect on the happiness of citizens when compared with government policies which strengthened and supported wider social networks. "People are less naive ( ) than one would expect, politicians need to adapted their policies and target specific problems in specific areas," she said.

PROBLEM: Article: Recipients of this year's Annenberg scholarships were announced on June 19. Brittany Blythe was one of them. In seventh grade,Brittany Blythe dreamed of being a cheerleader . Her school's coaches were less than enthusiastic. "They said. 'I don't know how you'll be able to do it'. "she recalls. "'You won't be able to do it'." But Brittany,now a junior at Strath Haven High School near Philadelphia,refused to give up.

When she tried to walk, her legs twisted. After the operation, she adapted quickly. "From day one,I basically jumped up and wanted to do everything,'' she says.

Other children laughed at her through the years,especially in junior high school,but she says the challenge only made her stronger. Now she's trying to convince her coaches to let her remove the prostheses and be a flyer. The cheerleader who's thrown in the air and caught by her teammates. Brittany doesn't think her problems put her at a disadvantage. "My disability was the first thing I had to get through., and that's going to prepare me for the future. "she says. "It's all just a test:If someone throws you a difficult problem,what are you going to do?"
