A practical scientific find:
As I have been thinking much about evolution lately and about how its mechanisms guides some of our behavior as persons and as whole societies, I found the above result interesting.
I wonder if this has to do with Muslims fasting in Ramadan tending to stay up all night after they break their fast at sunset. Of course, they do so to have their “so7or” late at night, but do they become too awake and party late into the night because of the food clock taking over the regular daylight clock or is this simply a middle Eastern cultural phenomena? Some statistics would help.
