Did you know that if you let fruit ferment, then you eat it, you can get really, really sick? While that’s true for humans, the fermentation process isn’t as harsh on our animal friends, meaning that they’re able to eat the fruit without having to do all the extra bits that we need to to make it palatable.

It turns out, they really like doing it, too — so much so that scientists now believe chimpanzees are in a constant state of mild buzz.

According to a recent study, while chimps don’t overserve themselves, they also don’t shy away from fermented fruit. This results in them consuming the equivalent of about two drinks over the course of their feeding — not enough to make them fall out of their trees, but enough to give them a little extra calmness for their future adventures.
