One thing that's often overlooked is that there are specific triggers that set off a mid-life crisis. Death of a family, loss of a job, empty nest, major birthday, etc. Usually a major life change that has the individual re-evaluating their lives.
If there isn't that trigger, then it's just bad behavior. Oftentimes people just look at how the WAS is acting and saying "ah it's MLC!". Without realizing that there are other factors that need to be considered.
Again Dr. Jim Conway is a great source to learn more.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
