Jojo the gorilla spent his life alone. Will he finally be able to find a companion?

This is a sign of a dysfunctional stress response. When a primate – a human, chimpanzee or gorilla – is stressed, blood flow to the eyes and ears increases. This puts them on alert for danger, but leaves their noses temporarily colder. For Jojo, this “nasal immersion”, as it is called, does not seem to be recovering.
