“Until about ten years ago, we admired those who could survive on only four hours of sleep and those stalwarts who worked through the night. They were heroes, people whose fierce devotion and commitment revealed everyone else’s fecklessness and frailty. Then, as sleep science reached the mainstream, we began to change our attitude. That sleepless guy wasn’t a hero. He was a fool. He was likely doing subpar work and maybe hurting the rest of us because of his poor choices. Breaks are now where sleep was then. Skipping lunch was once a badge of honor and taking a nap a mark of shame. No more. The science of timing now affirms what the Old World already understood: We should give ourselves a break.”
