Thirty-one million Americans are over 60 years of age, and twenty-nine million of them are healthy, busy, productive citizens. By the year 2030, one in every five people in the United States will be over 60. Elderly people are members of the fastest-growing minority in this country. Many call this the "graying of America". In 1973, a group called the "Gray Panthers" was organized. This group is made up of young and old citizens. They are trying to deal with the special problems of growing old in America. The Gray Panthers know that many elderly people have health problems; some cannot walk well, others cannot see or hear well. Some have financial problems; prices are going up so fast that the elderly can’t afford the food, clothing, and housing they need. Some old people are afraid and have safety problems. Others have emotional problems. Many elderly are lonely because of the death of a husband or a wife. The Gray Panthers know another fact, too. Elderly people want to be as independent as possible. So, the Gray Panthers are looking for ways to solve the special problems of the elderly. The president of the Gray Panthers is Maggie Kuhn, an active woman in her late 70s. She travels across the United States, educating both young and old about the concerns of elders. One of the problems she talks about is where and how elders live. She says that Americans do not encourage elders to live with younger people. As far as Maggie Kuhn is concerned, only elders who need constant medical care should be in nursing homes. Maggie Kuhn knows that elders need education, too. She spends lots of time talking to groups of older Americans. She encourages them to continue to live in their own houses if it is possible. She also tells them that it is important to live with younger people and to have children around them. This helps elders to stay young at heart. One of the problems Maggie Kuhn talks about is ______.

Children attending schools located in high-traffic zones have a 45 percent increased risk of developing asthma, even though time spent at school only accounts for about one-third of a child’s waking hours, according to new research. Asthma is the most common chronic childhood illness in developed countries and has been linked to environmental factors such as traffic-related air pollution. "While residential traffic-related pollution has been associated with asthma, there has been little study of the effects of traffic exposure at school on new onset asthma," says Rob McConnell, professor of preventive medicine at USC’s Keck School of Medicine. "Exposure to pollution at locations other than home, especially where children spend a large portion of their day and may engage in physical activity, appears to influence asthma risk as well." The study appears online in the journal Environmental Health Perspectives. The study drew upon data from the Children’s Health Study (CHS), a longitudinal study of children in Southern California communities that was designed to investigate the chronic effects of air pollution on respiratory health. Using a cohort of 2 497 kindergarten and first grade children who were asthma-free when they entered the study, researchers examined the relationship of local traffic around schools and homes to diagnosis new onset asthma that occurred during three years of follow-up. Traffic-related pollution exposure was assessed based on a model that took into account traffic volume, distance to major roadways from home and school and local weather conditions. Regional ambient ozone, nitrogen dioxide (二氧化氮) and particulate matter were measured continuously at one central site in each of the 13 study communities. The design allowed investigators to examine the joint effects of local traffic-related pollution exposure at school and at home and of regional pollution exposure affecting the entire community. Researchers found 120 cases of new asthma. The risk associated with traffic-related pollution exposure at schools was almost as high as for residential exposure, and combined exposure accounting for time spent at home and at school had a slightly larger effect. Although children spend less time at school than at home, physical education, and other activities that take place at school may increase ventilation rates and the dose of pollutants getting into the lungs, McConnell notes. Traffic-related pollutant levels may also be higher during the morning hours when children are arriving at school. Despite a state law that prohibits school districts from building campuses within 500 feet of a freeway, many Southern California schools are located near high-traffic areas, including busy surface streets. "It’s important to understand how these micro-environments where children spent a lot of their time outside of the home are impacting their health," McConnell says. "Policies that reduce exposure to high-traffic environments may help to prevent this disease. " The study was funded by grants from the National Institute of Environmental Health Sciences, the US Environmental Protection Agency, the South Coast Air Quality Management District, and the Hastings Foundation.
