Mid-life crisis usually is in the age range of 45-64. For men it can last 3-10 years. For women it can last 2-5 . The causes are aging itself, or aging in combination with life changes, problems or regrets over work, career (or lack thereof), spousal relationships (or lack thereof). Its components can be depression, remorse, anxiety. Some deal with it by chasing youthfulness. Others by making drastic changes in lifestyle/atmosphere. It sounds very scary to me. Does it to thee?
