What If You Never Had to Sleep Again?

What if you just… stopped getting sleepy? No yawns, no naps, no alarm clock. Eight spare hours a day, 56 extra hours a week, about four extra months of being awake every year. Leo, 28, gets exactly that. Three weeks later it's 3:12 AM, his little sister Anna has a fever, the hospital is 11 km away… and she's counting streetlights. Fourteen. Fifteen. Seventeen. So where did sixteen go? This animated "What If" story follows the superpower of never sleeping, then looks at the real science: microsleeps, Randy Gardner's 11 days awake, brain cells that nap on their own, dolphins that sleep with half their brain, and frigate birds that nap while flying. ⚠️ Feeling alert isn't the same as being alert. Drowsy at the wheel? Pull over somewhere safe, or hand someone the keys. 💬 Would YOU give up sleep? And which superpower should we test next?
