Have you ever gone camping where you wake and sleep with the sun and moon? Have you played outside all morning, only coming in when you get hungry for lunch? What was life like before we could measure time? How have clocks changed our behaviors — our work, our play, our sleep, our values, our expectations, our cultures — as humans?

We don’t sleep when we’re tired, we sleep when it’s time to sleep.”

Is this true for you? How have different technologies changed your days and nights? Watch these next: Borrowed Light and Carl Sagan’s Cosmic Calendar.
