Interesting story.

As Buddy fell away, Ollie began dragging St. James's mutilated body down a walkway. The 62-year-old man was conscious but near death. He had lost his nose, an eye, most of his fingers, both testicles and much of the flesh from his buttocks and face and left foot, but the chimp was not done with him yet.
I think that´s a pretty good reason to stay away from wild animals.
