Society Working on the night shift can change your outlook on our societal habits.
Most people rise with the sun and sleep at night.
In ancient times, it was the rule. Today, however, our societal tendencies toward a solar dependant schedule seem inefficient and obsolete. In ancient times, it was not safe to go out at night. People conducted their business during the day and hurried home as nightfall approached. There really was no reason to venture out at night in those times.
