Which of the following is NOT a stage of life mentioned in the content?

The concept of a "Midlife Crisis" is not classified as a distinct stage of life, but rather is considered a psychological phenomenon or transition that can occur during midlife. Stages of life typically represent broader, more defined periods characterized by common developmental challenges and changes, such as growth, maturation, and aging.

Early Adulthood, Late Adulthood, and Infancy are all recognized stages that reflect significant developmental milestones and challenges. Each of these stages encompasses physical, emotional, and social changes that are essential to understanding human development. In contrast, a midlife crisis is often viewed as an individual's experience of emotional turmoil or self-reflection during midlife, which may vary greatly from person to person and does not define a specific developmental stage.
