Gerontology in the context of "Gerontechnology"

Death is the end of life, the irreversible cessation of all biological functions that sustain a living organism. Death eventually and inevitably occurs in all organisms. The remains of a former organism normally begin to decompose shortly after death. Some organisms, such as Turritopsis dohrnii, are biologically immortal; however, they can still die from means other than aging. Death is generally applied to whole organisms; the equivalent for individual components of an organism, such as cells or tissues, is necrosis. Something that is not considered an organism can be physically destroyed but is not said to die, as it is not considered alive in the first place.

As of the early 21st century, 56 million people die per year. The most common reason is aging, followed by cardiovascular disease, which is a disease that affects the heart or blood vessels. As of 2022, an estimated total of almost 110 billion humans have died, or roughly 94% of all humans to have ever lived. A substudy of gerontology known as biogerontology seeks to eliminate death by natural aging in humans, often through the application of natural processes found in certain organisms. However, as humans do not have the means to apply this to themselves, they have to use other ways to reach the maximum lifespan for a human, often through lifestyle changes, such as calorie reduction, dieting, and exercise. The idea of lifespan extension is considered and studied as a way for people to live longer.

The social environment, social context, sociocultural context or milieu refers to the immediate physical and social setting in which people live or in which something happens or develops. It includes the culture that the individual was educated or lives in, and the people and institutions with whom they interact. The interaction may be in person or through communication media, even anonymous or one-way, and may not imply equality of social status. The social environment is a broader concept than that of social class or social circle.

The physical and social environment is a determining factor in active and healthy aging in place, being a central factor in the study of environmental gerontology.

Old age is the range of ages for people nearing and surpassing life expectancy. People of old age are called old people, the elderly, elders, senior citizens, seniors, or older adults. Old age is not a definite biological stage: the chronological age denoted as "old age" varies culturally and historically. Some disciplines and domains focus on the aging and the aged, such as the organic processes of aging (senescence), medical studies of the aging process (gerontology), diseases that afflict older adults (geriatrics), technology to support the aging society (gerontechnology), and leisure and sport activities adapted to older people (such as senior sport).

Old people often have limited regenerative abilities and are more susceptible to illness and injury than younger adults. They face social problems related to retirement, loneliness, and ageism.

Medical sociology is the sociological analysis of health, Illness, differential access to medical resources, the social organization of medicine, Health Care Delivery, the production of medical knowledge, selection of methods, the study of actions and interactions of healthcare professionals, and the social or cultural (rather than clinical or bodily) effects of medical practice. The field commonly interacts with the sociology of knowledge, science and technology studies, and social epistemology. Medical sociologists are also interested in the qualitative experiences of patients, doctors, and medical education; often working at the boundaries of public health, social work, demography and gerontology to explore phenomena at the intersection of the social and clinical sciences. Health disparities commonly relate to typical categories such as class, race, ethnicity, immigration, gender, sexuality, and age. Objective sociological research findings quickly become a normative and political issue.

Early work in medical sociology was conducted by Lawrence J Henderson whose theoretical interests in the work of Vilfredo Pareto inspired Talcott Parsons' interests in sociological systems theory. Parsons is one of the founding fathers of medical sociology, and applied social role theory to interactional relations between sick people and others. Later other sociologists such as Eliot Freidson have taken a conflict theory perspective, looking at how the medical profession secures its own interests. Key contributors to medical sociology since the 1950s include Howard S. Becker, Mike Bury, Peter Conrad, Jack Douglas, Eliot Freidson, David Silverman, Phil Strong, Bernice Pescosolido, Carl May, Anne Rogers, Anselm Strauss, Renee Fox, and Joseph W. Schneider.

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 people. Rather, this decision is guided by individual patient needs and the caregiving structures available to them. This care may benefit those who are managing multiple chronic conditions or experiencing significant age-related complications that threaten quality of daily life. Geriatric care may be indicated if caregiving responsibilities become increasingly stressful or medically complex for family and caregivers to manage independently.

There is a distinction between geriatrics and gerontology. Gerontology is the multidisciplinary study of the aging process, defined as the decline in organ function over time in the absence of injury, illness, environmental risks or behavioral risk factors. However, geriatrics is sometimes called medical gerontology.

Biogerontology is the sub-field of gerontology concerned with the biological aging process, its evolutionary origins, and potential means to intervene in the process. The term "biogerontology" was coined by S. Rattan, and came in regular use with the start of the journal Biogerontology in 2000. It involves interdisciplinary research on the causes, effects, and mechanisms of biological aging. Biogerontologist Leonard Hayflick has said that the natural average lifespan for a human is around 92 years and, if humans do not invent new approaches to treat aging, they will be stuck with this lifespan. James Vaupel has predicted that life expectancy in industrialized countries will reach 100 for children born after the year 2000. Many surveyed biogerontologists have predicted life expectancies of more than three centuries for people born after the year 2100. Other scientists, more controversially, suggest the possibility of unlimited lifespans for those currently living. For example, Aubrey de Grey offers the "tentative timeframe" that with adequate funding of research to develop interventions in aging such as strategies for engineered negligible senescence, "we have a 50/50 chance of developing technology within about 25 to 30 years from now that will, under reasonable assumptions about the rate of subsequent improvements in that technology, allow us to stop people from dying of aging at any age". The idea of this approach is to use presently available technology to extend lifespans of currently living humans long enough for future technological progress to resolve any remaining aging-related issues. This concept has been referred to as longevity escape velocity.

Biomedical gerontology, also known as experimental gerontology and life extension, is a sub-discipline of biogerontology endeavoring to slow, prevent, and even reverse aging in both humans and animals.

Something that is not considered an organism may be said to die in a figurative sense when it reaches an inactive state, such as when a star runs out of fuel.
