What If You Never Needed to Sleep?

You get eight extra hours every day and never feel tired. It sounds like the ultimate superpower. Then the endless nights start taking the one thing sleep was quietly protecting all along. In this episode, you wake up one Tuesday and never need sleep again. At first it's incredible — 2,920 extra hours a year, almost four extra months. You finish books, learn piano, double your income, and go viral. But then the days stop ending. Your keys end up in the fridge, your memories stop sticking, and the people you love fall asleep while you're still on duty. The science inside: why your brain runs in 90-minute sleep cycles, how adenosine builds sleep pressure (and why caffeine blocks it), the 2013 glymphatic discovery that your brain cleans itself while you sleep, Randy Gardner's 264 hours awake in 1964, and the 2010 review on sleep and memory.
