What perspective does the man adopt after he falls for the last time?

a. He accepts the idea of death.

He had been running around like a chicken with its head cut off. He was certain to freeze in his present circumstances, and he should accept it calmly. With this newfound peace of mind came the first sleepiness. A good idea, he thought, to sleep his way to death. Freezing was not as bad as people thought. There were many worse ways to die.
