But what about simple, everyday moments? What happens to those memories?

"And the answer is really straightforward: they are lost forever. I mean, most of the moments of our life and I calculated, you know, the psychological present is said to be about three seconds long. That means that in a life there are about 600 million of them, in a month there about 600,000. Most of them don’t leave a trace. Most of them are completely ignored by the remembering self. And yet, somehow you get the sense that they should count, that what happens during these moments of experience is our life. It’s the finite resource that we’re spending while we’re on this Earth. And how to spend it would seem to be relevant. But that is not the story that the remembering self keeps for us."
