A better understanding of how sleep knits our memories together could lead to new technologies
that improve learning, memory and creativity, and even help treat some psychiatric disease. But
perhaps the most important reason for studying sleep is simply this: we are a curious species; we
spend about a third of our lives asleep; and we realize how little we understand about that third of
our lives. So we continue experimenting, hoping to understand sleep better. And perhaps
someday we will. After we've slept on it.
