In psychology, midlife refers to the stage of life between young adulthood and old age, typically characterized by a sense of transition and reevaluation. It is a period of life where individuals may experience significant changes in their physical, emotional, and social well-being,, and may re-evaluate their life goals and priorities.

Examples of midlife in psychology may include:

  1. Physical changes: During midlife, individuals may experience changes in their physical health and well-being, such as menopause or andropause, a decrease in muscle mass and bone density, and an increased risk of chronic health conditions.

  2. Emotional changes: Midlife may be a time of emotional upheaval, with individuals experiencing a range of emotions such as anxiety, depression, or a sense of loss or regret.

  3. Career changes: Many individuals in midlife may re-evaluate their career choices, considering a change in direction or pursuing new opportunities.

  4. Family changes: Midlife may also be a time of change in family dynamics, with children leaving the home or parents requiring care, and individuals may need to adapt to new roles and responsibilities.

  2. Jungian psychology: This approach emphasizes the importance of individuation, or the process of becoming one's true self, and recognizes midlife as a time of increased self-awareness and growth.

  3. Gerontology: This is the study of aging and older adults, with a focus on the physical, social, and psychological changes that occur during the aging process.
