As anyone is different from others ,it appears that individual takes different methods to arrange their time for having rest .I prefer to go to sleep early and wake up early when sun raise .    I have seen a documentary which demonstrate that during the long period of evolution ,human developed a biologic clock which ensure individual have a deep sleep at night and wake up at morning .If some one don't obey this nature rule,as a consequence he will find he need more sleep to compensate the low quality of sleeping .Recently ，there is a news concerning a car accident in which the driver drove the car at night and fall asleep though he had slept at daytime.Sometimes you just can't resist sleeping when the environment is dark.    In the other hand ,though individual could make timetable for himself ,he can not decide other's life.To some extent  ,our life is not only ourselves as we lived in a big society where communication is needed .So when we take part in group works we need to share time with others who usually wake up at morning and starts day's work.Except one condition that all the members all work until late night.A good example of social communication needs decide our time table is that all the company which require group work like Apple and Google require their employees to attend work at day time .Maybe the only group work at late night is rock band.
  I am sure that there is some job demand people staying up late like DJ in night club and some one who working on research would do the job more efficiency at late nigh .But to most ordinary people ,obey to the nature will never be wrong.
