Human beings seem to be fighting the evolutionary pressure to sleep.
Despite the fact that sleep plays a vital part in our health and our efficiency, we seem out to abolish sleep. The first step in this process was the invention of the electric lightbulb, which eliminated our main excuse for stopping work at the end of the day, namely, that it was too dark to function. Next came the continuous conveyor belt, which encouraged factories to operate 24 hours a day. Now the continuous access to information provided by the Internet and other computer communication links keeps us from our beds at all hours of the night. The work ethic we have adopted today says that we should do away with sleep, or at least eliminate as much sleep time as possible.
