Both apes and humans suffer from midlife crisis..

A superb read from Andrew Oswald

Humans suffer from mid life crisis around 45-47:

Happiness is approximately U-shaped across a person’s life. It has been known for more than two decades by behavioural scientists and wellbeing researchers that human happiness and mental health appear to follow a large, looping, U-shaped trajectory through the main part of people’s lives (cf. Feddersen, Metcalfe, and Wooden 2012). This statistical pattern has been found in dozens of countries.

  • People as young adults start happy.
  • Then comes a downhill patch for approximately two decades.

Both men and women go through their 40s at the lowest psychological ebb; the literal bottom usually hits around age 47 – so, sorry if that’s your next birthday.

  • After mid-life, things look up.

People roar up the right-hand side of the U shape through their 50s and 60s. Contentment accelerates. The young just do not realise how enjoyable it is to be old (as long as you are in decent health).

 Well apes also suffer from the same. Though as they live shorter, their midlife crisis come earlier:

I and the global team from Edinburgh (including Alex Weiss), Arizona and Kyoto, released a paper showing that the great apes have a similar ‘midlife crisis’ to that in humans, and thus that our closest biological relatives also trace out the U shaped happiness over the lifespan. The parallels between the two curves are close; humans live to about a maximum of 100-110 years, and apes live at to a maximum of about 50-55 years. We have our midlife low just before 50, apes have theirs around their late 20s.

In our study we collected data on 508 orangutans and chimpanzees in 65 zoos across a wide range of nations. We recorded the keepers’ assessments of the psychological well-being of the animals. Each ape has several keepers, and every keeper was asked to assess the psychological well-being of their particular animal using a short questionnaire (including my favourite: “If you were that animal how happy do you think you would be on a scale of 1-7?”). We then averaged these responses, checking for consistency.

 What use for economics..Well it is connection to the happiness economics:

If you’re not a scientist, why would you care?

One implication as to why the finding of the U shape in ape happiness is important is that it might help you, or those around you, understand, empathise or sympathise with those experiencing midlife crises. The consumption of antidepressants in Europe is highest among those in their mid-40s, a telling sign that we might want to assure those we know that are going through midlife that their crisis is, at least in part, ‘natural’.

And if apes go through similar emotional turmoils to ours, they probably deserve more respect from human beings than they get.

Hmm..Refreshing read..

    good one. It means that when a relatively large portion of a country’s population is in its mid 40s, the country would undergo a psychological transition. The marginal propensity to save would reduce and wages would go up, for people would save less and work less too.
