A mid-life crisis is a period of emotional turmoil that some individuals experience during middle adulthood, typically between the ages of 40 and 60. It often involves feelings of uncertainty, dissatisfaction, and a desire for change, as people reflect on their life achievements and future goals. This phase can lead to significant life changes, such as career shifts, relationship reevaluations, or new hobbies. The concept of a mid-life crisis was popularized by psychologist Elliott Jaques in the 1960s. While not everyone experiences this crisis, it can be triggered by various factors, including aging, health issues, or major life events, prompting individuals to reassess their priorities and aspirations.
