What is the Meaning of Life?

To what lengths would I travel to protect the ones I love? What does love mean? Why do we strive to survive and reproduce? What is the point of living? When is it a good time to loose all hope and surrender? Is there a moral line I would not cross in a life v. death situation? Would I resort to cannibalism if it were the only way for me to continue to live? Is life a stumbling, random walk through the world? Does Karma exist? Is there a God? or Two? Does it matter?

Reading books like The Road, by Cormac McCarthy, makes me ponder such questions. I never get any answers, just questions. Such irritating and depressing questions.
