Functional age is ability-based; chronological age is years lived. Which term is used for the age measure based on abilities?

• A. Years lived
• B. Functional death
• C. Functional age
• D. Crystallized intelligence

Answer: (C)

Functional age is the age measure based on abilities. It looks at how well someone can perform daily activities, mobility, self-care, and cognitive function, which can differ from the number of years someone has lived. Chronological age is simply years lived, while functional age reflects actual functioning and health status. A person can be older by calendar years but functionally younger if they maintain good physical and cognitive abilities, and vice versa. The other terms don’t fit: years lived describes chronological age; functional death isn’t a standard age measure; crystallized intelligence refers to accumulated knowledge, not a way to gauge age.
