Document Summary
Time embedded in our genes; biological clocks found everywhere (bacteria, worms, us) Biological clock medical implication = action of drugs vary depending on time of day. No time cues our rhythms slowly drift out of alignment with outside world. Natural world= fully of daily, monthly, annual rhythms. Daily circadian rhythms are orchestrated by a central clock to keep our bodily systems working in harmony, but if disrupted = suffer mild symptoms of jet lag to serious conditions such as depression and sleep disorders. Clock keep ensemble of body beating to a collective time = keeps everything from happening all at once and ensures biochemistry of body runs on time and in order. Biological clock impose structure that enables organisms to change their behavioural priorities in relations to time of day, month, or year = reset at sunrise and sunset each day to link astronomical time with organism"s internal time. Today; 24/7 society = employed in utilities, transport, retail, etc.
