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.

Nations around the world are experiencing a spectacular increase in longevity. Society as a whole is being challenged by issues arising from this revolution in longevity. Although the specter of the loneliness and existential suffering of older citizens is such that some people under the age of 65 find it difficult to conceive of a long-term future, persons over 85 have proven that aging does not necessarily preclude a healthy and productive life. Extraordinary progress in both curative and preventive medicine justifies optimism about the quality of life and state of well-being that can be enjoyed even in great old age. We should look to professionals in diverse fields to develop creative solutions to the inevitable issues that will arise with aging. Governments must prepare for the future health of their citizens by making long-term investments to educate all sectors of society in the value of good nutrition, exercise, and lifestyles that enhance well-being throughout life. Also, governments should realize that the main cause of health care expenditure is serious illness which occurs in persons of all ages, and not predominantly in older people. Early detection can help save lives, as well. Health and longevity of life will ultimately end as a political issue. What is needed is long-term government investments necessary for a viable health policy. The question arises: will world leaders be able to commit to such a policy? Two major socioeconomic phenomena may have a regulating effect on this issue. The first is the emergence of pressure groups that have come into being in response to a particular health issue, such as AIDS. The second is the emergence of ethics committees in developed nations that deal solely with health issues.

In 1950 men and women in the United States had a combined life expectancy of 68.9 years, the 12th highest life expectancy at birth in the world. Today, life expectancy is up to 79.2 years, yet the country is now 28th on the list, behind the United Kingdom, Korea, Canada, and France, among others. The United States does have higher rates of infant mortality and violent deaths than in other developed countries, but these factors do not fully account for the country's relatively poor ranking in life expectancy. International Differences in Mortality at Older Ages: Dimensions and Sources examines patterns in international differences in life expectancy above age 50 and assesses the evidence and arguments that have been advanced to explain the poor position of the United States relative to other countries. The papers in this deeply researched volume identify gaps in measurement, data, theory, and research design and pinpoint areas for future high-priority research in this area. In addition to examining the differences in mortality around the world, the papers in International Differences in Mortality at Older Ages look at health factors and life-style choices commonly believed to contribute to the observed international differences in life expectancy. They also identify strategic opportunities for health-related interventions. This book offers a wide variety of disciplinary and scholarly perspectives to the study of mortality, and it offers in-depth analyses that can serve health professionals, policy makers, statisticians, and researchers.

Pulitzer-prize winning author Dr. Robert Butler coined the term "ageism" and made "Alzheimer's" a familiar word. Now he brings his formidable knowledge and experience in aging issues to a recent and unprecedented achievement: the extension of human life expectancy by thirty years. As Butler shows, our society had not yet adapted to this change. The U.S. has not made a research investment in aging. Only eleven medical schools out of 145 have geriatrics departments compared to England where geriatrics is the number two specialty. We have not solidified private pension plans or strengthened Social Security to ensure that people do not outlive their resources. In this urgent and ultimately optimistic book, Dr. Butler shows why and how we must re-examine our personal and societal approach to aging right now, so that the boomers and the generations that follow may have a financially secure, vigorous, and healthy final chapter life.

States that the number of genuine long-livers is exploding and a substantial proportion of new-borns in developed countries may survive to celebrate their 100th birthday. This book examines the storied realms of exceptional longevity.

Oldness: a social construct at odds with reality that constrains how we live after middle age and stifles business thinking on how to best serve a group of consumers, workers, and innovators that is growing larger and wealthier with every passing day. Over the past two decades, Joseph F. Coughlin has been busting myths about aging with groundbreaking multidisciplinary research into what older people actually want -- not what conventional wisdom suggests they need. In The Longevity Economy, Coughlin provides the framing and insight business leaders need to serve the growing older market: a vast, diverse group of consumers representing every possible level of health and wealth, worth about $8 trillion in the United States alone and climbing. Coughlin provides deep insight into a population that consistently defies expectations: people who, through their continued personal and professional ambition, desire for experience, and quest for self-actualization, are building a striking, unheralded vision of longer life that very few in business fully understand. His focus on women -- they outnumber men, control household spending and finances, and are leading the charge toward tomorrow's creative new narrative of later life -- is especially illuminating. Coughlin pinpoints the gap between myth and reality and then shows businesses how to bridge it. As the demographics of global aging transform and accelerate, it is now critical to build a new understanding of the shifting physiological, cognitive, social, family, and psychological realities of the longevity economy.

Longevity with Joy This book, Longevity with Joy, was written mainly to improve the quality of life from birth to a ripe old age. We are globally living longer. Good news! The author already enumerated and discussed the factors contributing to living longer in some parts of the world in this book. As a result, she wrote this book from the research and investigations made on quality, long life. It is not living long that really matters but the quality of the longevity. The author was born and bred in Nigeria. Despite the factors that militated against her survival and education, she got educated, taught in postprimary schools, and worked in the Ministry of Health before she left for Dublin, Ireland, in January 1999. She went further to study health care and ICT. Evangeline Omini has been a writer since 1992. Her latest book, "God's Love Prevails," was published by Xlibris in USA in 2013.
