Early to bed early to rise ... depends on the TV schedule in your time zone

A recent study published in the Journal of Labor Economics found that television schedules have a larger impact on people's daily routines than natural daylight patterns. The research reveals that Americans' sleep and work patterns are shaped by artificial time zones and TV broadcast schedules, rather than the sun's cues.
