The Rare Ancient DNA Of People Who Only Sleep 4 Hours Alberto Genovese [9B3UuDT0syj]

What if your body only needed six hours to do what everyone else's body needs eight for?

That's the reality for a tiny group of people called natural short sleepers and thanks to a decade of genetic research, scientists finally know why. This video unpacks the discovery of DEC2, the first gene ever linked to short sleep, found in 2009 by UCSF neurologist Dr. Ying-Hui Fu. We look at real cases like Ce Mei Chao, who runs liga mx on four to five hours a night with zero crash, and unpack the strange side effects that seem to come with the mutation: sharper memory, higher pain tolerance, motherwell vs hearts and immunity to jet lag.

But this isn't a video telling you to sleep less. We also cover why this mutation is likely a recent development in human history rather than an ancient trait, why editing your own genes to gain it isn't close to reality, circle k gas station 40 cents off and what the science actually says happens to your immune system, hormones, and heart when someone without the mutation tries to live on four hours anyway. The honest answer, for almost everyone watching, is that less sleep isn't a hack it's a cost.
