Milife crisis is a term used in Western societies to describe a period of dramatic self-doubt that is felt by some individuals in the "middle years" of life, as a result of sensing the passing of youth and the imminence of old age. Sometimes, transitions experienced in these years, such as aging in general, menopause, the death of parents, or children leaving home, can trigger such a crisis. The result may be a desire to make significant changes in core aspects of day to day life or situation, such as in career, marriage, or romantic relationships.
