Mid-career crises do not discriminate

The age-related curve in job satisfaction has been found in more than 50 countries. It affects senior-level executives as well as blue-collar workers, stay-at-home parents, childless couples and single people.

Generally, life satisfaction is high when people are young, it starts to decline in the early 30s and is the lowest between mid-40s and mid-50s. Then it increases again to levels as high as during young adulthood.
