Try to imagine life without timekeeping. You probably can't.
You know the month, the year, the day of the week. There is a clock on your wall or the dashboard of your car. You have a schedule, a calendar, a time for dinner or a movie. Yet, all around you, timekeeping is ignored. Birds are not late. A dog does not check it's watch. Deers do not fret over passing birthdays. And, because of this, man alone suffers a paralyzing fear that no other creature endures.
A fear of time running out.
