Some genetic mutations appear to accelerate certain features of aging only within a single tissue. There are a very large number of these conditions, which might be referred to as unimodal progeroid syndromes. Here only three examples are considered: one that has a major impact on sun-exposed skin, one that results in an early onset of the most common form of dementia alzheimer, Alzheimer’s disease, and another that results in early-onset Parkinson’s disease.

Depression in late life is closely linked with senescence at a very basic level. Before discussing medical illness and disease processes, however, it will be helpful to review some more basic processes that may trigger, or at the very least exacerbate, depression through biochemical or neuroanatomical mechanisms.

Social cognitions involve thoughts about others and thoughts about the self in relationship to others. When we consider cognitive aging theory from this point of view, it leads us away from traditional research methods and theoretical perspectives that have focused on basic information processing and how it is tied to physiological decline. This body of research has been largely experimental and often has taken place in situations designed to remove the effects of the social context. In contrast, research on social cognition and aging typically is designed to consider how social context affects the thinking of adults. (more…)

Though much psychological research traditionally has focused on problems and maladjustment, recently there has been more interest in positive psychology, qualities that promote personal well-being across the life span. In this section, several of the positive aspects of later life social cognition that have received attention within personality psychology are briefly discussed. These include generativity, ego integrity and coping, optimism and perceived control, and wisdom. (more…)

Aging is not only about old age. This is an ongoing process which will define the stages of biological, psychological and social conditions in human lives. Aging has limit for averages human life expectancy rate. For centuries, many have tried modern science to delay human life expectancy rate so much from this frightening condition of man. There are millions of websites on the internet providing information on aging and more than half a million consultations related searches information on how to alter averages human life expectancy rate.

It is never too late to promote life span extension through sensible diet. A study shows that a strict low-calorie diet can promote life span of mice more than 40 percent. Many studies have shown that using this method on starting young mice on a diet with calorie restriction can help them live months longer than animals fed a standard diet. But the new study shows that even 19 months old mice can be comparable to 60 and 65 years of life in human. Those can be achieved by eating fewer calories. (more…)

Your potential average and maximum life spans will be substantially increased by the nutrient-rich food.

Let’s say that your hereditary potential the age you might expect to reach based upon the genes you’ve inherited from your parents is to live to be 80 years old. Let’s assume that you started and stuck to a rather high percentage of calorie limit, beginning at age 20. Over that remaining 60 years you might expect to age at half the expected rate, be “functionally” 50 when you were in fact chronologically 80. Your 60 years would thus stretch out to 120. (more…)

Aging theories cover the physiological, genetic, biochemical properties of a typical organism, and the way these properties change with time. Theories of genetic dealing with the identity of aging obesity genes, accumulation of errors in the genetic machinery, programmed senescence, and telomeres theory. Biochemical theories are concerned with generation of free radicals, the rate of living, energy metabolism, and the health of mitochondria. While Theory of Physiological deal most entirely with the endocrine system and the purpose of hormones in governing the rate of cellular aging. (more…)
