“Natural” is overrated
or, why Soylent is A Good Thing
Humans evolved mainly to be active during daytime and to rest and sleep when it’s dark — the duration of those “days” and “nights” being fixed in ecuatorial Africa long ago. The natural thing for us, humans of the 21st century, would be to go to bed around sunset, and get up when the sun rises.

However, not all humans can do that, all the time. Someone has to watch museums, factories and streets at night. A&E needs to be staffed. Someone has to work in the wee hours to bake the bread you eat for breakfast. People live in high latitudes, where nights are very short in the summer and very long in the winter. People travel and have a hard time adapting their sleep cycle to a new time zone.
