Apparently, a bear ransacked his camp and destroyed most of his equipment before his German shepherd chased the wild beast off. He survived for three months before rescuers discovered him and airlifted his emaciated body to hospital. He remains in a serious condition after he lost half his body weight and the ability to speak while in the grips of hypothermia. There is little plant life to eat in that part of the wild, and he was slowly dying. When a person gets hungry, they have mood swings and they cramp all over the body while the body canalizes itself.

Unless we are in a similar situation, none of know, really know, how we'd cope. I for one would rather die than betray a friendship and kill a companion. But that's just me.
Maybe you rate yourself above an animal.
