What term describes aging differences caused by health habits, genes, and other personal factors, resulting in more variability across individuals?

• A. Primary aging
• B. Secondary aging
• C. Physiological aging
• D. Tertiary aging

Answer: (B)

Aging differences that come from health habits, genes, and other personal factors reflect secondary aging. This recognizes that while some changes are part of the overall aging process, individuals diverge in how much those changes show up because of lifestyle, genetics, and environment, leading to more variability in how people age. Primary aging, by contrast, refers to universal, time-related changes that affect everyone more or less similarly, so it contributes less to differences between individuals. Tertiary aging describes a rapid decline in function late in life, and physiological aging is not the standard term used to describe this variability pattern. So, the idea that personal factors drive varied aging experiences best fits secondary aging.
