Old age

Old age is the range of ages for people nearing and surpassing life expectancy. People of old age are also referred to as: old people, elderly, elders, seniors, senior citizens, or older adults.^[1] Old age is not a definite biological stage: the chronological age denoted as "old age" varies culturally and historically.^[2] Some disciplines and domains focus on the aging and the aged, such as the organic processes of aging (senescence),^[3] medical studies of the aging process (gerontology),^[4] diseases that afflict older adults (geriatrics),^[5] 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.^[6]^[7]

In 2011, the United Nations proposed a human-rights convention to protect old people.^[8]
