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.

Some statistics would help.
