Which group consists of healthy, vigorous older adults aged roughly 60-75 who are well integrated into families and communities?

• A. Wear and tear
• B. Old-old
• C. Oldest-old
• D. Young-old

Answer: (D)

Older adulthood is often categorized by how active and independent people are, not just by age. The description fits the young-old group, who are typically healthy, vigorous, and still closely connected to family and community life, roughly around ages 60 to 75. The old-old and oldest-old groups refer to those who are older and more likely to experience health declines, while wear-and-tear is a theory about why aging happens, not a demographic group. So the best answer is the young-old.
