According to the Oxford Dictionary, “old age” refers to the later part of life, typically characterized by the gradual decline in physical and mental abilities. It is often associated with a stage of life that follows middle age, usually beginning around the age of 65. The term encompasses various aspects, including the physical, psychological, and social changes that individuals experience as they age. Old age can also imply a period of wisdom and experience, although it may bring challenges such as health issues and societal changes. Overall, the definition reflects a complex phase of human life shaped by multiple factors.
