In The Law of Life, how does Koskoosh die? How was he expected to die?

In London's "The Law of Life," Koskoosh is expected to freeze to death, most likely, to starve, or to be killed and eaten by animal predators.

In the society of the story, everyone is expected to contribute to the tribe.  Once a person cannot contribute, he is left behind when the tribe moves, and it is expected that he will die.

Koskoosh is no exception.  He is left to die.  He is expecting to freeze, but in the end, wolves find him, and he is about to be attacked and eaten as the story ends.

This of course seems extremely harsh by us in our world of social security and medicare and welfare, etc., but in the tribe of the story, the tribe's survival depends on everyone contributing.
