Overall most of our lives are based on the 9-5 work cycle, and we get up go to work, eat, sleep, and bathe, then do it all over again. The funny situation is that isn't normal. In most of our history, we got up at the crack of dawn, or perhaps whenever we wanted to, then we got whatever work needed to be done that done, done. There was no time constraints, or limiting factors to our daily lifestyle. On top of that there was much less stress on each individual person.
