Narrator: How much of our past lives, the thousands of moments we experience, helps to make us who we are? If you took all of these remembrances, these memories, away, what would be left? How much is our personality, our identity, determined by the experiences we have, and how much is already there - pure "us"?
Doug Bruce: I see memory as, as somthing akin to, you know, traveling in time. And everybody's got this ability to, you know, to travel in time, just by going back to places in the past that they experienced or whatever.... And I don't have that.
