Ageing

Ageing (or aging in American English) 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 a broader sense, ageing can refer to single cells within an organism which have ceased dividing, or to the population of a species.

Geriatrics, or geriatric medicine, is a medical specialty focused on addressing the unique health needs of older adults. The term geriatrics originates from the Greek γέρων geron meaning "old man", and ιατρός iatros meaning "healer". It aims to promote health by preventing, diagnosing and treating disease in older adults. Older adults may be healthy, but they're more likely to have chronic health concerns and require more medical care. There is no defined age at which patients may be under the care of a geriatrician, or geriatric physician, a physician who specializes in the care of older peop

Gerontophobia is the hatred or fear of older adults, or a fear of age-related self-degeneration (similar to gerascophobia). The term comes from the Greek γέρων – gerōn, "old man" and φόβος – phobos, "fear". Gerontophobia that stems from a fear of aging has been linked to thanatophobia, as fear of old age can be a precursor to fear of death. Gerontophobia can be caused by stereotypes of older adults displayed in the media.

Gerascophobia is an abnormal or incessant fear of growing older or ageing (senescence). Fear is characterised as an unpleasant emotion experienced as a result of some perceived threat or source of danger, in the case of gerascophobia that threat is ageing. This fear is irrational and disproportionate to any threat posed and persists even in the case that the individual is in perfect health.

A geroprotector aims to affect the root cause of aging and age-related diseases, and thus prolong the life span of animals. Some possible geroprotectors include melatonin, carnosine, metformin, rapamycin, nicotinamide mononucleotide (NMN), delta sleep-inducing peptide,glycine, and psilocin.

Gerontechnology, also called gerotechnology is an inter- and multidisciplinary academic as well as a professional field that combines various disciplines of gerontology and technology. Sustainability of an aging society depends on our effectiveness in creating technological environments, including assistive technology and inclusive design, for innovative and independent living and social participation of older adults in any state of health, comfort as well as safety. In short, gerontechnology concerns matching technological environments to health, housing, mobility, communication, leisure, wor

In the United States, the FDA bans Gerovital H3 from interstate commerce as an unapproved drug and, since 1982, has prohibited its importation.

A Lebenstreppe or Stufenalter (German: "steps of life" or "stages of life") is a pictorial representation of the human life as a series of ascending and descending steps. The tradition began in fifteenth-century Europe and many hundreds of variations were produced until the early twentieth century, though the popularity of the tradition waned during the nineteenth century. The most common variation depicts ten steps each representing ten years, with the peak at fifty. Parodic versions have been created for satiric, moralistic, and advertising purposes.

Inflammaging (also known as inflamm-aging or inflamm-ageing) is a chronic, sterile, low-grade inflammation that develops with advanced age, in the absence of overt infection, and may contribute to clinical manifestations of other age-related pathologies. Inflammaging is thought to be caused by a loss of control over systemic inflammation resulting in chronic overstimulation of the innate immune system. Inflammaging i
