Old age is the range of ages for people approaching and past life expectancy, with those in this stage referred to as old people, the elderly, seniors or older adults. It is not a fixed biological stage, since the age at which a person is considered old varies by culture and historical period. Aging is studied by several fields, including gerontology, the medical study of aging, and geriatrics, which focuses on diseases affecting older adults. People of old age typically have reduced regenerative ability and greater susceptibility to illness and injury than younger people, and they often face social challenges such as retirement, loneliness and ageism.
