It is common ground accepting an average 8 hours, but this is just apply as a framework to resting our bodies.
In a broader sense, each person has a different machine to take care of, and different interests, so if you have something that moves you deeply or a think you like to work in... you just keep doing it.
The opposite comes from doing thinks you dont like: boredom or madness result from that.
I know people that sleep about 5 hours and have a very energetic day to day life, but also it is easy to find sort of calmed people, that dont react to external impulses fast, but keep their mind in a peaceful state that let them sleep 2 or 3 times a day, with a siesta, a longer nite, and a small after work sleeping, just to attend their life requirements.
How can you make every person to fit a single pair of shoes??
7 Hours a day.
