All of us will face periods of transition in our lives which involve particular challenges. Some psychological adjustments relate not so much to external events, but to more internal challenges, perhaps associated with life stages and the aging process. Early last century Carl Jung spoke of psychological challenges which occur in our lives around mid-life, around 40 years of age give or take two or three years or after around 13 years of marriage.  It is commonly a period of both upheaval and potential growth.
