Chimpanzees
and orangutans may experience a "mid-life crisis" like humans, a
study suggests.
An
international team of researchers assessed the well-being and happiness of the
great apes.
They
found well-being was high in youth, fell to a low in midlife and rose again in
old age, similar to the "U-shape curve" of happiness in humans.
The
study brought together experts such as psychologists, primatologists and
economists.
Results
are published in the Proceedings of the
National Academy of Sciences.
"What
we are testing is whether the U-shaped curve can describe the association
between age and well-being in non-human primates as it does in humans,"
psychologist and lead author Dr Alexander Weiss of the University of Edinburgh
told BBC Nature.
Dr
Weiss hoped the results would show a similar curve because of the close
relationship between humans, chimpanzees and orangutans.
