Final answer:
Functional age is the age that indicates the actual competence and performance of older adults and may be higher or lower than chronological age.
Step-by-step explanation:
The age that indicates the actual competence and performance of older adults and may be higher or lower than chronological age is called functional age.
Functional age refers to how well an individual can perform everyday tasks and activities, such as physical, cognitive, and social activities, compared to individuals of the same chronological age.
For example, a 70-year-old who is physically fit, mentally sharp, and socially active may have a functional age that is younger than their chronological age, while a 70-year-old who struggles with physical limitations, cognitive decline, and social isolation may have a functional age that is older than their chronological age.
