Well, I just now looked at the original article, and while another "comment" mentions that the photo "looks bad," honestly, as one who has dealt with some grizzly injuries on humans, myself, and animals, to me that facial injury does not look so bad at all.
If his entire face had been mauled, like what happened to the woman that the Chimpanzee got a hold of, then I’d say he had some serious problems. However, this is not the case, and his injury, though deep, is nothing more than the size of of the guy’s eyeball.
Yes, it’s scarey looking with all that blood smeared about, but in reality, it’s not that big of a deal, barring infections.
