A human life is often divided into various ages.Historically, the lifespan of man was divided into seven ages; because biological changes are slow moving and vary from person to person, arbitrary dates are usually set to mark periods of human life.Cultural variations
In some cultures (for example Serbian and Russian) there are two ways to express age: by counting years with or without including current year.Advanced age is given more respect and status.Legal
There are variations in many countries as to what age a person legally becomes an adult.These ages include voting age, drinking age, age of consent, age of majority, age of criminal responsibility, marriageable age, age where one can hold public office, and mandatory retirement age.Admission to a movie for instance, may depend on age according to a motion picture rating system.Similarly in many countries in jurisprudence, the defense of infancy is a form of defense by which a defendant argues that, at the time a law was broken, they were not liable for their actions, and thus should not be held liable for a crime.Economics and marketing
The economics of aging are also of great import.They also have considerable impact on how their parents spend money.They do not yet have set buying habits and are more open to new products.The young are thus the central target of marketers.Movies are also built around appealing to the young.Western Europe and Japan, have aging populations.While the effects on society are complex, there is a concern about the impact on health care demand.Cognitive effects
Steady decline in many cognitive processes are seen across the lifespan, starting in one's thirties.Psychologists have examined coping skills in the elderly.Religion
Religion has been an important factor used by the elderly in coping with the demands of later life, and appears more often than other forms of coping later in life.Various reasons have been proposed for this association; people who are objectively healthy may naturally rate their health better than that of their ill counterparts, though this link has been observed even in studies which have controlled for socioeconomic status, psychological functioning and health status.Retirement
Retirement, a common transition faced by the elderly, may have both positive and negative consequences.Societal impact
Societal aging refers to the demographic aging of populations and societies.Cultural differences in attitudes to aging have been studied.Older adults are better at regulating their emotions and experience negative affect less frequently than younger adults and show a positivity effect in their attention and memory.Terminology
The concept of successful aging can be traced back to the 1950s, and popularised in the 1980s.Previous research into aging exaggerated the extent to which health disabilities, such as diabetes or osteoporosis, could be attributed exclusively to age, and research in gerontology exaggerated the homogeneity of samples of elderly people.Successful aging may be viewed an interdisciplinary concept, spanning both psychology and sociology, where it is seen as the transaction between society and individuals across the life span with specific focus on the later years of life.Modernization Theory
This is the view that the status of the elderly has declined since industrialization and the spread of technology.Cognitive Theory
A view of aging that emphasizes individual subjective perception, rather than actual objective change itself, as the factor that determines behavior associated with advanced age.Political Economy Theory
A societal perspective on the aging process that explains that the status and resources of the elderly, as well as how people age, are shaped by each person's place in the social structure and the economic and political forces that impact their sociopolitical location.Disengagement Theory
This is the idea that separation of older people from active roles in society is normal and appropriate, and benefits both society and older individuals.Disengagement theory, first proposed by Cumming and Henry, has received considerable attention in gerontology, but has been much criticised.The original data on which Cumming and Henry based the theory were from a rather small sample of older adults in Kansas City, and from this select sample Cumming and Henry then took disengagement to be a universal theory.There are research data suggesting that the elderly who do become detached from society as those were initially reclusive individuals, and such disengagement is not purely a response to aging.Activity Theory
In contrast to disengagement theory, this theory implies that the more active elderly people are, the more likely they are to be satisfied with life.Activity and Disengagement Theory, which suggests that it may benefit older people to become more active in some aspects of their lives, more disengaged in others.Continuity Theory
The view that in aging people are inclined to maintain, as much as they can, the same habits, personalities, and styles of life that they have developed in earlier years.Shortened telomeres activate a mechanism that prevents further cell multiplication.Cell Cycle Theory
The idea that aging is regulated by reproductive hormones that act in an antagonistic pleiotrophic manner via cell cycle signaling, promoting growth and development early in life in order to achieve reproduction, but later in life, in a futile attempt to maintain reproduction, become dysregulated and drive senescence (dyosis).Tear theory
The idea that changes associated with aging are the result of chance damage that accumulates over time.Autoimmune Theory
The idea that aging results from an increase in autoantibodies that attack the body's tissues.Clock Theory
The theory that aging results from a preprogrammed sequence, as in a clock, built into the operation of the nervous or endocrine system of the body.In rapidly dividing cells the shortening of the telomeres would provide just such a clock.Radical Theory
The idea that free radicals (unstable and highly reactive organic molecules, also named reactive oxygen species or oxidative stress) create damage that gives rise to symptoms we recognize as aging.Recently, Michael Ristow has shown that this delay of aging is due to increased formation of free radicals within the mitochondria causing a secondary induction of increased antioxidant defence capacity.Alternatively, fertilization age, beginning from fertilization can be taken.Age is often rounded downward to an integer, where the time of birth is taken to have been 0:00 (in other words, the number of days is first rounded upward, before rounding downward to whole years).Look up aging in Wiktionary, the free dictionary.Physiological Basis of Aging and Geriatrics, By Paola S.Does Age Quash Our Spirit of Adventure?.Windsor TD, Anstey KJ, Butterworth P, Luszcz MA, Andrews GR (2007).Rodin J, Langer EJ (1977).Handbook of the Psychology of Religion and Spirituality.Rated Health, Gender, and Mortality in Older Persons: Introduction to a Special Section".Sarah Harper, 2006, Aging Societies: Myths, Challenges and Opportunities.Rowe JW, Kahn RL (1987).Fentleman, DL (1990), Successful aging in a postretirement society; in Baltes, Margret M.Cambridge, UK: Cambridge University Press.New York, NY: HarperCollins College Publishers.Schulz TJ, Zarse K, Voigt A, Urban N, Birringer M, Ristow M (2007).Gerontological Theory: The Search for the Holy Grail.San Diego, CA, USA, 2006.Human aging: Usual and successful.The Gerontologist, 42, (6)
