Oh, Sheriff Bell. What a card. Here, our old boy uses a bit of black humor to lighten the mood. And it's funny because it's true. We can't imagine that the lifespan of your average drug runner is a long one. Chigurh is the exception: he might never die. But he's almost more of a symbol than a real person.

Bell suspects that drug runners are the result of the natural evolution of cattle rustlers. If that's true, then what's the next step? Where will these guys go when the drug business is no longer profitable? Or will it always be profitable?

In brief sentences like these, we think "thought about his life" is a shorthand way of saying "considering the choices he has made to lead him here." But do you think Llewelyn regrets them?
