"Leben ist die schonste Erfindung der Natur und der Tod ist ihr Kunstgriff, viel Leben zu haben" . J. W. v. Goethe Life is the most beautiful invention of nature, and death is her device to exhibit most life. The eminent British biologist Sir Vincent B. Wigglesworth noted in 1939 that insects are an ideal medium in which to study all problems of physiology. Many fundamental discoveries in biology, particularly genetics and development, have been made on the basis of studies conducted in insects. Because of their ex treme adaptability and diversity, an appropriate insect model is available for the study of virtually any biological problems. The applicability to other groups, including mammals, of basic studies conducted on insects has helped in the gradual acceptance of the fundamental unity of biochemical principles as a dogma among biologists, as well as among enlightened medical scientists. With the recent upsurge of interest in the study of the aging process, in sects have been increasingly employed not only for the investigation of basic mechanisms of aging, but also to gain insight into the evolution of aging and senescence. If only one aging mechanism exists, it is foreseeable that some in sects, especially Drosophila, will help to unravel its molecular basis. Because of their diversity, existing studies in the gerontology of insects are widely scat tered in various specialized journals. This wealth of existing information has not, as yet, been brought together in a synthesized and comprehensive form.

During the last 25 years, life expectancy at age 50 in the United States has been rising, but at a slower pace than in many other high-income countries, such as Japan and Australia. This difference is particularly notable given that the United States spends more on health care than any other nation. Concerned about this divergence, the National Institute on Aging asked the National Research Council to examine evidence on its possible causes. According to Explaining Divergent Levels of Longevity in High-Income Countries, the nation's history of heavy smoking is a major reason why lifespans in the United States fall short of those in many other high-income nations. Evidence suggests that current obesity levels play a substantial part as well. The book reports that lack of universal access to health care in the U.S. also has increased mortality and reduced life expectancy, though this is a less significant factor for those over age 65 because of Medicare access. For the main causes of death at older ages-cancer and cardiovascular disease-available indicators do not suggest that the U.S. health care system is failing to prevent deaths that would be averted elsewhere. In fact, cancer detection and survival appear to be better in the U.S. than in most other high-income nations, and survival rates following a heart attack also are favorable. Explaining Divergent Levels of Longevity in High-Income Countries identifies many gaps in research. For instance, while lung cancer deaths are a reliable marker of the damage from smoking, no clear-cut marker exists for obesity, physical inactivity, social integration, or other risks considered in this book. Moreover, evaluation of these risk factors is based on observational studies, which-unlike randomized controlled trials-are subject to many biases.
