Book Description
A central concept in the evolutionary theory of senescence is the idea that ageing results from life-history trade-offs. In particular, the disposable soma theory suggests that longevity is determined through the setting of longevity assurance mechanisms so as to provide an optimal compromise between investments in somatic maintenance (including stress resistance) and in reproduction. Comparative studies among mammalian species confirm that cells from long-lived species appear to have a greater intrinsic capacity to withstand stresses than cells from short-lived species. Childbearing at older ages has become increasingly common in modern societies because of demographic changes, medical progress and personal choice. While the detrimental effects of late reproduction on infant mortality and genetic diseases have been well documented, little is known about the possible postponed detrimental effects of late parenting.

Book Description
Explore international trends in health and longevity--with a special focus on older women! This essential book examines the latest research on life expectancy and “active life expectancy”--the number of years that women can expect to live free from major disability--in developed and developing countries around the world. It also explores the policy implications of the contributors’ findings. Here you'll find a global study using data from the World Health Organization, a European study using data from OECD countries, and studies of women in the United Kingdom, Fiji, The Netherlands, Japan, Canada, and the United States. With contributions from demographers, economists, epidemiologists, gerontologists, medical statisticians, policy analysts, physicians, public health directors, and sociologists, International Perspectives on Health Expectancies for Older Women compares mortality and morbidity trends in various populations. In addition to reviewing the current literature on active life expectancy, this informative book looks at: the distribution of total, unimpaired, and impaired life for several groups of older women defined by race, education, and marital history gender differences in health profiles in The Netherlands gender differences in life with and without six major diseases, including both morbid and mortal conditions in the United States how mortality and morbidity patterns differ for Canadian women and men 45 years of age and older, focusing on risk factors and chronic conditions such as low income, low education, abnormal body mass index, lack of physical activity, smoking, cancer, diabetes, and arthritis patterns of healthy life expectancy for older women around the globe a comparison of the development and progression of physical disability in Japanese men and women and more!

Book Description
Converging evidence from disciplines including sociobiology, evolutionary psychology and human biology forces us to adopt a new idea of what it means to be a human. As cherished concepts such as free will, naïve realism, humans as creation's crowning glory fall and our moral roots in ape group dynamics become clearer, we have to take leave of many concepts that have been central to defining our humanness. What emerges is a new human, the homo novus, a human being without illusions. Leading authors from many different fields explore these issues by addressing a range of illusions and providing evidence for the need, despite considerable reluctance, to relinquish some of our most cherished ideas about ourselves.

Book Description
After decades of systematic collection of data describing age-related changes in organisms, organs, tissues, cells and macromolecules, biogerontologists are now in a position to construct general principles of ageing and explore various possibilities of intervention using rational approaches. While not giving serious consideration to the claims made by charlatans, it cannot be ignored that several researchers are making genuine attempts to test and develop various means of intervention for the prevention and treatment of age-related diseases, for regaining the functional abilities and for prolonging the lifespan of experimental organisms. This book provides the most up-to-date information and a critical evaluation of a variety of approaches being tried for modulating aging and longevity, including dietary supplementation with antioxidants, vitamins and hormones, genetic engineering, life-style alterations, and hormesis through mild stress. The goal of research on ageing is not to increase human longevity regardless of the consequences, but to increase active longevity free from disability and functional dependence.

Book Description
In this third volume on longevity Fondation Ipsen has again collected the most recent results in research on genes and diet in the evolution of human longevity, educational level and longevity, cognitive impairment and survival at older age and other contributions. The preponderance of relatively short - compared to long-lived organisms suggests that morphogenesis is easier to accomplish than is maintenace of soma, whereas the broad range of longevities of organisms demonstrates that maintaining soma for extended periods of time is possible. The underlying assumption of "disposable soma" theory of aging is that the expense of maintaining somatic cells depends on their contribution to the welfare of the germ cells.

Book Description
This book is a point-of-care resource for effective sexual and reproductive healthcare for patients of all ages, sexual orientations, gender identities and medical backgrounds in the primary care setting. This useful guide is divided into three parts, and other than part three, which deals exclusively with transgender and gender diverse patients, all content will relate to patients of all gender identities. Part one presents sexual and reproductive health (SRH) using a lifespan approach, including chapters on pediatrics, adolescents and young adults, adults, and older adult patients. Part two presents an approach to common SRH issues that span multiple age groups, including contraception and family planning, sexually transmitted infections and cancer screenings as well as sexual and reproductive health in the setting of common medical conditions. Part three is dedicated to sexual and reproductive health for transgender and gender non-binary patients, including psychosocial, medical, surgical and legal aspects of health. This book provides primary care clinicians with a framework for providing effective sexual and reproductive healthcare to patients of all ages, sexual orientations and gender identities in a way that is inclusive, focuses on health, and addresses the needs unique to specific populations.

Book Description
The scientific debate on longevity and its determinants is lively and involves researchers from different some people live longer than others is not an easy task. Variables that are shown to be significant for longer survival in certain populations are not always relevant to individuals of other populations. Recently, researchers have identified in Sardinia the Blue Zone (BZ), thus denominated due to the significant number of cases of centenarians recorded as well as a low sex ratio value. A village located in this area was selected for the carrying out of a more detailed analysis at individual level and socio-demographic determinants of longevity were examined. A family reconstructed database was created using a multi-source approach. Historical data was therefore used to study today's population, establishing a unique bridge between historical demography and the current level of longevity. The study focused on survival of newborns in the selected village during a period of 50 years – from 1866 to 1915 – and also took into consideration information on related family members. Each individual included in the database was followed from birth to death, as he/she went through marriage and family formation. Complete survival of all newborns was observed until the present. Based on careful review of the existing literature, the empirical model considered factors such as sex differential, the contribution of familial transmission both in terms of genes, biological, and shared environment, and the role played by environment operationalised considering early-life conditions. Concepts were organized into a life-course approach for survival analysis. The analysis of the data enabled to the estimation of mortality trajectories, which in turn confirmed the exceptional longevity of the population understudy and in particular of males. The investigation of differential survival among members of the same community brought to light the relevance of certain familial variables on survival, which are not exclusively genetic. The results achieved open the way to further studies.
