Question

Quizplus · Accepted Answer

Middle adulthood, typically considered to range from approximately 40 to 65 years of age, does not have more concrete boundaries than infancy, childhood, and adolescence. The transitions into and out of middle adulthood are often defined more by individual experiences, such as changes in health, career, or family dynamics, rather than by clear biological or social markers. In contrast, infancy, childhood, and adolescence are more commonly delineated by specific developmental milestones and age ranges.
