Which aging concept is described as a holistic view of an individual based on cellular aging?

• A. Normative aging
• B. Contextual aging
• C. Mechanistic aging / biological model
• D. Organismal aging

Answer: (D)

Organismal aging captures aging as a whole-person phenomenon, tying what happens at the cellular level to how the entire body functions over time. It looks at how cellular aging contributes to changes across organ systems, mobility, cognition, and independence, and explains why the aging person as a single integrated unit experiences aging. That holistic viewpoint is why this option fits best.

Other options describe different aspects: normative aging is about typical timelines and patterns that occur with age; contextual aging emphasizes environmental and social factors shaping aging; mechanistic aging focuses on the biological processes at the cellular or molecular level without necessarily linking them to the whole-person experience.
