Long Hair Could Rob Brain Energy?

The North Korean government (search) is telling men with long hair to cut their locks, insisting that long hair "consumes a great deal of nutrition" and could rob men’s brains of energy.
Announcements on state-run media say men should not let their hair grow longer than five centimeters and two haircuts a month is recommended.
After all, the announcements say, looking tidy is "important in repelling the enemies' maneuvers to infiltrate corrupt capitalist ideas and lifestyle [into North Korea]," and "people who ... live in others' style become fools, and [their] nation will come to ruin."

Women with long hair are okay. After all, you don't want them to be smarter than the men.
