What If You Stopped Needing Sleep?

It's 3 AM, everyone's asleep, and you feel amazing. You haven't slept in days, and you don't need to. What could possibly go wrong? This episode, you stop needing sleep. The sand in your brain's hourglass never piles up, the night shift of brain-cleaning happens while you're awake, and you get eight extra hours every single day. That's an extra day every three days, and about twenty-five extra years over a lifetime. Languages, instruments, empty streets at 4 AM. A whole secret city all to yourself. Then the scientists show up. We look at the real biology of sleep: adenosine, your brain's grain-of-rice-sized clock, Randy Gardner's 11-day record from 1964 and the rare people who really do need less sleep. And we look at what sleep was quietly doing for you all along. Because when everyone else in the world is asleep, someone has to be awake. And one winter night, that turns out to matter more than anything.
