The New Science of Sleep
We live in a shortsighted society that sees sleep as an obstacle to productivity [Jan. 24]. But the truth is quite the opposite. A nightly investment in eight hours of rest may lead to even greater accomplishments. The greatest and most imaginative members of society, our children, sleep 10 to 12 hours a night. We should follow their lead. And we certainly shouldn't buy into romanticized notions of how much work we can do without sleep.
