The narrative describes a conversation between a father and his six-year-old son about sleep and death. The father explains that sleep is similar to death, as it leaves humans defenseless for hours. He also mentions different sleep requirements of various animals. The father then explains the stages of sleep, from the slowing of brainwaves to rapid eye movement.
The narrator then discusses the concept of death as a recurring theme in our lives, drawing parallels between it and an asteroid approaching our planet. The father encourages the son to view life as an experiment, a journey conducted across the entire planet and history, with humans as the experimenters.
The conversation concludes with the narrator expressing a sense of awe and gratitude for the brief period of time we have on Earth, and the importance of not wasting it. The narrator also shares a quote from Ursula K. Le Guin, suggesting that a journey of a thousand miles begins with a single step.
