Happiness If your sense of well-being fluctuates with stock market, you might be comforted to know that money can’t buy you happiness anyway. In one American study conducted in 1993, level of income was shown to have an inverse relation to happiness: The group whose income had declined was happier overall than the group whose income had increased. A soon-to-be published review of the hundreds of studies on this subject supports the 1993 findings. In developed countries, the correlation between income and happiness is close to zero and sometimes negative. With a correlation between level of income and happiness somewhere between 0.12 and 0.18, the United States is near the bottom of the list; that factors other than income are overwhelmingly more important in explaining happiness. Also, as our material wealth increases, the gap between income and satisfaction with life seems to be widening. Predictably, money has its most positive effect on the poor, but once a person has achieved a minimal standard of living level of income has almost nothing to do with happiness. Close relationship, rather than money, is the key to happiness. Indeed, the number of one’s personal friends is a much better indicator of overall satisfaction with life than personal wealth. One stands a better chance of achieving a satisfying life by spending time with friends and family than by striving for higher income. Incidentally, in the US, as people become richer, the probability of divorce increases. Our need for companionship is partly biological. All primates respond with pleasure to demonstrations of affection and with pain to loss of companionship. Isolated monkeys will sacrifice food just for the glimpses of another monkey. By ignoring our biologically programmed need for each other, we risk physical and mental distress. A recent cross-national study of mental depression in the US found that in advanced countries, there is a rising tide of major depression. Teenage suicides have increased in recent decades in almost all advanced countries. Moreover, in the US since World War II, there has been an actual decline in the proportion of people who report themselves to be "very unhappy." You can easily test the claim that companionship exceeds wealth as a source of happiness. Ask yourself which has a greater influence on your satisfaction with life: your income or the affection of your intimate companions and the well-being of your children Conversely, which would make you more depressed: a reduction in salary or a divorce and isolation from your friends Capitalism succeeds in creating material riches, but it is less successful in building companionable societies and protecting family integrity. But developing countries still have much work to do in pursuing material wealth, where a rise in productivity still greatly increases happiness. For poorer countries, the time is not yet ripe for a shift in priorities from wealth accumulation to companionship. Can we afford to believe that the pursuit of material gain will lead to self-fulfilhnent We should continue to enjoy our wealth in good company, or else we may find that it is not satisfying. According to the author, which of the following is most likely to share our biological need for companionship besides the monkey

Smoking Can Increase Depressive Symptoms in Teens While some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto and the University of Montreal have found that smoking may actually (51) depressive symptoms in some teens. "This observational study is one of the few to examine the perceived (52) benefits of smoking among teens," says lead researcher Michael Chatom, a research associate at the Ontario Tobacco Research Unit of the University of Toronto. " (53) cigarettes may appear to have self-medicating (54) or to improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms." As part of the study, some 662 high school teenagers completed up to 20 questionnaires (55) their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French and English participants, urban and rural schools, and schools (56) in high, moderate and low socioeconomic neighborhoods. Participants were divided into three (57) : never smokers; smokers who did not use cigarettes to self-medicate, improve mood or physical (58) ; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had (59) going to sleep or staying (60) ; felt unhappy, sad, or depressed; felt hopeless about the future; felt vexed, antsy or tense; and worried too much about things. "Smokers who used cigarettes as mood (61) had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O’Loughlin, a professor at the University of Montreal Department of Social and Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of (62) depressive symptoms." (63) between depression and smoking exists (64) among teens that use cigarettes to feel better. "It’s (65) to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.
Smart Window Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch. "It took us a long time to figure out what a window really is," says Claes Granqvist. He’s a professor of solid-state physics at Uppsala University in Sweden. "It’s contact with the outside world. You have to have visual contact with the surrounding world to feel well." So, windows and natural light are important for improving the way people feel when they’re stuck indoors. Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it’s hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world. Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color. electro chromic windows use electricity to change color. For example, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it’s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark. One important feature that makes a smart window so smart is that it has a sort of "memory." All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different. To make electrochromic windows change color, what is applied to the window glass
Lower Body Fat Means Better Performance These days, fashion models and pop stars are not the only people who have to watch their waistline. Football players who miss a few kicks and let their belly hanging out a little too much are likely to be attacked by rabid fans or even the president of a country. The latest football star to draw the attention of the "fat police" is Barcelona’s Ronaldinho, 26. Last Friday, a Spanish sports daily published two photos of the Brazilian star without his shirt. One was taken in November 2003; the other was taken this month. In the most recent one, the star’s waistline seems to have a little extra padding. Another Spanish sports daily published similar before-and-aider photos and argued that the star has "lost his explosiveness and velocity" and is "worn out". The cause, according to the news paper, is his poor physical fitness. However, the player’s coach, Frank Rijkaard, insists that he’s satisfied with Ronaldinho’s form and fitness. And after Barcelona’s victory over Athletic Bibao on Sunday, Ronaldinho challenged photographers to take pictures of him when he took off his shirt. "! don’t have anything to hide," he said. Fellow Brazilian Ronaldo, 30, of Real Madrid, faced similar criticism before the 2006 World Cup. But the criticism didn’t come from a bunch of sports reporters: It came from the president of Brazil. "So, what is it" Brazil’s President Luiz Inacio Lula da Silva asked the national soccer team’s coach in his office last June, according to the Associated Press. "Is he [Ronaldo] fat or not" "He is very strong, president," Carlos Alberto Parreira reportedly said at the time. "He is not that boy anymore. His body type has changed." The game of footfall demands that players put as much emphasis on fitness as they can do on dribbling, passing or shooting. During a proper training regimen, football players normally follow a load-fatigue-recovery pattern. They push their body toward a higher mark of fitness and experience a slight and brief drop in performance. Then they begin the recovery process, which will ideally carry their performance to an even higher plane. However, sometimes non-physical factors can influence a player’s poor fitness. In Ronaldinho’s case, for instance, people, often unnamed, have blamed everything from the pressure of contract negotiations to personal problems and too many advertising commitments. The football game demands a lot from players.
