Old age refers to ages nearing or surpassing the life expectancy of human beings, and is thus the end of the human life cycle.

In October 2016, a highly publicized paper claimed the maximum human lifespan is an average age of 115, with an absolute upper limit of 125 years, but the authors' methods and conclusions are controversial.

Terms and euphemisms for old people include, old people (worldwide usage), seniors (American usage), senior citizens (British and American usage), older adults (in the social sciences), the elderly, and elders (in many cultures—including the cultures of aboriginal people).

Health care or healthcare is the maintenance or improvement of health via the diagnosis, treatment, and prevention of disease, illness, injury, and other physical and mental impairments in human beings.

Healthcare is delivered by health professionals (providers or practitioners) in allied health professions, chiropractic, physicians, physician associates, dentistry, midwifery, nursing, medicine, optometry, pharmacy, psychology, and other health professions.

It includes the work done in providing primary care, secondary care, and tertiary care, as well as in public health.

A caregiver or carer is an unpaid or paid person who helps another individual with an impairment with his or her activities of daily living.

Any person with a health impairment might use caregiving services to address their difficulties.

Caregiving is most commonly used to address impairments related to old age, disability, a disease, or a mental disorder.

Health is the level of functional and metabolic efficiency of a living organism.

In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental or social changes.

The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies, and because of the problem created by use of the word "complete".

Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.
