The Science of Sleep. Sleep is one of the strangest things we do each day. The average adult will spend 36 percent of his or her life asleep. For one-third of our time on earth, we transition from the vibrant, thoughtful, active organisms we are during the day and power down into a quiet state of hibernation.
Sixty-three percent of those surveyed said they were very likely to work through their fatigue while on the job, while nearly one-third were very likely to use caffeinated beverages to stay alert. But 29 percent of respondents reported falling asleep or becoming very sleepy at work during the month before the survey. Another 12 percent were late to work because of sleepiness. Some courts have weighed in on workers who sued companies that fired them for sleeping on the job.
