Mental health problems of aging and the aged from the viewpoint of analytical psychology.

According to Jung's analytical psychology man is either predominantly extravert or predominantly introvert. Whichever he is, he must in most cases, in order to satisfy the biological drives of the earlier part of his life, adapt himself to an extraverted culture and thus become largely extravert. In the later part of life, as biological involution sets in, this attitude and the values attached thereto no longer suffice. The strains set up by the resulting need for a reorientation in life are a fruitful source of mental disorder.
