Summary

In the wild, dominant animals stress out their subordinates, according to textbook studies. But recent studies show the top dogs—as well as top dwarf mongooses, baboons, and other animals—have the highest levels of cortisol, a stress hormone. And habitually high cortisol levels may cost them years off their lives.
