Even a few of the commenters on this item on the Guardian on line seemed to think it was simply a subject to make jokes about. One said he hoped his tax dollars hadn’t been spent on the research. Some hope, does he think these studies are self funded by enthusiastic amateurs?
The study was published in the Proceedings of the National Academy of Sciences, and has been claimed by commentators to support the idea that we evolved from apes, or ape like ancestors, or hominids, or whatever. Stands to reason dunnit? Men have mid life crises, so do chimps, so obviously we must have evolved from them! So please renew our research grant, please.
The international researchers asked zookeepers and other 'carers' to complete questionnaires on the animals, commenting on their mood, social pleasure, success at achieving goals and how observers thought they would feel being in the apes’ skin.
Analysis allegedly showed that ape wellbeing declined in middle age and climbed again in old age.
