People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Great apes may have mid life crisis, a study suggests

RATE THIS! +6

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. The study showed that male and female humans, chimpanzees and orangutans have the same U-shaped curve despite differences in social roles, and the phenomenon is therefore not uniquely human.
