Everyone has heard of a midlife crisis but what about midlife misery?
According to a new study, 47.2 is the age at which people in the developed world are the most miserable.
Economics professor David Blanchflower, from Dartmouth College, studied data from 132 countries, including 95 developing countries, to explore the relationship between wellbeing and age.
The former Bank of England policymaker discovered there is a "U-curve" of happiness across every country he studied.
The average age at which happiness is lowest is 47.2-years-old.
"The curve's trajectory holds true in countries where the median wage is high and where it is not and where people tend to live longer and where they don't," Blanchflower wrote in a study distributed by the National Bureau of Economic Research.
