List six reasons Krakauer gives that explain why he included these autobiographical chapters into his study of Chris McCandless. Do you think these autobiographical chapters enhance the book? if so, how?

From the text:

As a youth, I am told, I was willful, self-absorbed, intermittently reckless, moody. I disappointed my father in the usual ways. Like McCandless, figures of male authority aroused in me a confusing medley of corked fury and hunger to please. If something captured my undisciplined imagination, I pursued it with a zeal bordering on obsession, and from the age of seventeen until my late twenties that something was mountain climbing.

In my opinion, Krakauer's own experiences give him a perspective of McCandless that most of us would never understand. Thus, they enhance the book by making us more aware of the reasons Chris may have acted in the way he did.
