Pawan’s Reviews > Why We Sleep: The New Science of Sleep and Dreams > Status Update

According to this book there are more morning larks than night owls, but I have known disproportionately more night owls. I had a notion that if minimum required downtime is H hours, then one could complete the sleep roster in multiple segments that sum cumulatively to H. That notion is unfounded. People involved in active decision making must undergo contiguous downtime.
