As long as there have been people who could not sleep, ways of getting to sleep have been suggested. According to Wikipedia, for over four hundred years a solution has been to count sheep. Identical sheep pass by, climbing over the low spot in a fence or wall. The insomniac counts each one, one-at-a-time.
Just as sure as night and day, sleep is a part of life – not just a part, but an integral part. It’s the way we are made. Machines can be made to run day-and-night weeks at a time, but not the human body.
