There’s a meme going around saying that a bed is just a padded shelf where we put our body when we’re not using it. The saying is oddly clever, but it doesn’t capture the fact that we don’t actually have a choice about sleeping. It’s going to happen. Consciousness wears us out, and then leaves us, despite our best efforts to force it to stay for the coffee and energy drinks. Eventually, we all need that shelf to serve as our wireless recharging station. Try as we might, even the strongest and fittest and most prominent humans can’t avoid shutting down regularly. For hours on end, we lie prostrate, vulnerable, and undignified on our beds, completely unaware and unable to work on our to-do lists and ambitions. Presidents snore. Queens drool on silk pillows. Celebrities wake up with bad breath and messy hair. Geniuses roll out of bed with foggy brains, groping for the coffee pot.
