The notion also comes up in the contrast between career and leisure activity whereby it may be suggested that gratification ought to occur after one has made oneself financially stable, and the subsequent contrasting views on the age range that ought to occur in. [2] In religions, such idealizations similarly exist with for instance quite detailed accounts on what the general age range of entrants of jannah (heaven) will be. [3] According to various hadiths, that age is 33 for men and 17 for women, with the presupposition that these ages augment the best of human attributes and that these ages do not change but remain constant since the biological process of ageing becomes obsolete. [4] Evaluations of a more critical nature tend to focus upon the fairness of prolonged periods of education for young people whereby in some subjects they only reap the rewards of their labour when they are middle aged, and thereby spend their prior younger years through various sacrificing stages. [5] In reflections on adventurous sex, there are at times indications of a specific age targeted due to a perception that this particular age range has the most feasible pragmatism as an audience whether for physiological or practical purposes.

Axiology is the philosophical study of value. It includes questions about the nature and classification of values and about what kinds of things have value. It is intimately connected with various other philosophical fields that crucially depend on the notion of value, like ethics, aesthetics or philosophy of religion. It is also closely related to value theory and meta-ethics. The term was first used by Paul Lapie, in 1902, and Eduard von Hartmann, in 1908.
In the field of psychology, cognitive dissonance is the perception of contradictory information. Relevant items of information include a person's actions, feelings, ideas, beliefs, values, and things in the environment. Cognitive dissonance is typically experienced as psychological stress when persons participate in an action that goes against one or more of those things. According to this theory, when two actions or ideas are not psychologically consistent with each other, people do all in their power to change them until they become consistent. The discomfort is triggered by the person's belief clashing with new information perceived, wherein the individual tries to find a way to resolve the contradiction to reduce their discomfort.
Old age refers to ages nearing or surpassing the life expectancy of human beings, and is thus the end of the human life cycle. Terms and euphemisms for people at this age include old people, the elderly, OAPs, seniors, senior citizens, older adults, and the elders.
Gerontology is the study of the social, cultural, psychological, cognitive, and biological aspects of aging. The word was coined by Ilya Ilyich Mechnikov in 1903, from the Greek γέρων, geron, "old man" and -λογία, -logia, "study of". The field is distinguished from geriatrics, which is the branch of medicine that specializes in the treatment of existing disease in older adults. Gerontologists include researchers and practitioners in the fields of biology, nursing, medicine, criminology, dentistry, social work, physical and occupational therapy, psychology, psychiatry, sociology, economics, political science, architecture, geography, pharmacy, public health, housing, and anthropology.
Population ageing is an increasing median age in a population because of declining fertility rates and rising life expectancy. Most countries have rising life expectancy and an ageing population, trends that emerged first in developed countries but are now seen in virtually all developing countries. That is the case for every country in the world except the 18 countries designated as "demographic outliers" by the United Nations. The aged population is currently at its highest level in human history. The UN predicts the rate of population ageing in the 21st century will exceed that of the previous century. The number of people aged 60 years and over has tripled since 1950 and reached 600 million in 2000 and surpassed 700 million in 2006. It is projected that the combined senior and geriatric population will reach 2.1 billion by 2050. Countries vary significantly in terms of the degree and pace of ageing, and the UN expects populations that began ageing later will have less time to adapt to its implications.
Consumer behavior is the study of individuals, groups, or organizations and all the activities associated with the purchase, use and disposal of goods and services. Consumer behaviour consists of how the consumer's emotions, attitudes, and preferences affect buying behaviour. Consumer behaviour emerged in the 1940–1950s as a distinct sub-discipline of marketing, but has become an interdisciplinary social science that blends elements from psychology, sociology, social anthropology, anthropology, ethnography, marketing, and economics.
Product design as a verb is to create a new product to be sold by a business to its customers. A very broad coefficient and effective generation and development of ideas through a process that leads to new products. Thus, it is a major aspect of new product development.
Cosmetic advertising is the promotion of cosmetics and beauty products by the cosmetics industry through a variety of media. The advertising campaigns are usually aimed at women wishing to improve their appearance, commonly to increase physical attractiveness and reduce the signs of ageing.
The theory of positive disintegration (TPD) by Kazimierz Dąbrowski is a theory of personality development.
Age appropriateness refers to people behaving as predicted by their perspective timetable of development. The perspective timetable is embedded throughout people's social life, primarily based on socially-agreed age expectations and age norms. For a given behavior, such as marrying, entering school, etc., there are years within which the behavior is regarded appropriate. By contrast, if the behavior falls out of the age range, it will be considered age-inappropriate. Most people are adhered to these age norms and are aware of whether their timing is "early," "delayed," or "on time."
Ageing (BE) or aging (AE) is the process of becoming older. The term refers mainly to humans, many other animals, and fungi, whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal. In broader senses, ageing can refer to single cells within an organism which have ceased dividing, or to the population of a species.
Customer experience (CX) is a totality of cognitive, affective, sensory, and behavioral consumer responses during all stages of the consumption process including pre-purchase, consumption, and post-purchase stages. Pine and Gilmore described the experience economy as the next level after commodities, goods, and services with memorable events as the final business product. Four realms of experience include esthetic, escapist, entertainment, and educational components.
Storage of wine is an important consideration for wine that is being kept for long-term aging. While most wine is consumed within 24 hours of purchase, fine wines are often set aside for long-term storage. Wine is one of the few commodities that can improve in flavour and value with age, but it can also rapidly deteriorate if kept in inadequate conditions.
The self-discrepancy theory states that individuals compare their "actual" self to internalized standards or the "ideal/ought self". Inconsistencies between "actual", "ideal" and "ought" are associated with emotional discomforts. Self-discrepancy is the gap between two of these self-representations that leads to negative emotions.
Madhu Sudan Kanungo was an Indian scientist in the field of gerontology and neuroscience as well as a teacher of molecular biology and biochemistry. He is known for his theories on how gene expression changes with age and the role of this phenomenon in ageing, which is a widely accepted as "Gene expression theory of Aging". In recognition of his contributions, he was awarded India's fourth highest civilian award, Padma Shri in 2005. He held the post of BHU Emeritus professor in zoology at the Banaras Hindu University and was also the Chancellor, Nagaland University till his death.
P. Eline Slagboom is a Dutch biologist specializing in the human familial longevity and ageing.
Elder rights are the rights of older adults, who in various countries are not recognized as a constitutionally protected class yet face discrimination across many aspects of society due to their age.
Ageing studies is a field of theoretically, politically, and empirically engaged cultural analysis that was developed by scholars from many different disciplines. Over the past fifteen years the field of ageing studies has flourished, with a growing number of scholars paying attention to the cultural implications of population ageing.
The mutation accumulation theory of ageing was first proposed by Peter Medawar in 1952 as an evolutionary explanation for biological ageing and the associated decline in fitness that accompanies it. Medawar used the term 'senescence' to refer to this process. The theory explains that, in the case where harmful mutations are only expressed later in life, when reproduction has ceased and future survival is increasingly unlikely, then these mutations are likely to be unknowingly passed on to future generations. In this situation the force of natural selection will be weak, and so insufficient to consistently eliminate these mutations. Medawar posited that over time these mutations would accumulate due to genetic drift and lead to the evolution of what is now referred to as ageing.
In Inuit culture, sipiniq refers to a person who is believed to have changed their physical sex as an infant, but whose gender is typically designated as being the same as their perceived original sex. In some ways, being sipiniq can be considered a third gender. This concept is primarily attested in areas of the Canadian Arctic, such as Igloolik and Nunavik. The Netsilik Inuit used the word kipijuituq for a similar concept.
