What term describes the view of aging as a process by which the body wears out over time and environmental stressors?

• A. Genetic clock
• B. Cellular aging
• C. Wear and tear
• D. Changes in brain functioning

Answer: (C)

The main idea here is the wear-and-tear view of aging. This perspective treats aging as the gradual wearing down of the body due to time and the cumulative impact of environmental stressors like sunlight, pollution, toxins, and other daily wear. Over years, repeated damage to cells and tissues accumulates, leading to functional decline and the visible signs of aging. It’s about deterioration from use and exposure rather than a pre-programmed timetable or aging that occurs strictly at the cellular level. This makes the wear-and-tear option the best answer because it directly describes aging as a process of the body wearing out from time and environmental stress. By contrast, the genetic clock implies aging is predetermined by genetics, cellular aging centers on cells themselves rather than external wear, and changes in brain functioning focus on cognitive changes rather than the broad process of overall bodily wear.
