Today researchers realize that many human characteristics, from basic physiological functions such as blood pressure and body temperature to mental sharpness and moods, follow such patterns. Some...
More sensible work schedules could reduce such hazards. In a recent eleven- month experiment in Philadelphia, police were put on a revised rotation that meshed better with their innate clocks.
