I don't think some people are less smart than others; sometime, they are just bound by condition of life at certain location or country...
If you let this fisher try an automobile, it won't take long before he could drive it. But here, along the road from Ninh Binh to Phu Ly, I caught this photo while he was trying to earn some tiny fishes for family dinner. This method of fishing may be invented several generations before him, and may last several more generations after...
Actually, I felt the same as you do about the fisher's face. I regret that he was working too hard, trying to monitor any sound of fish in his trap. The bad news is, I waited for more than 20 minutes and he caught nothing... so he never raised his head before I left.
THE PROBLEM IS , I THINK, THERE IS SO MUCH CONFUSION BECAUSE THE FOREGROUND AND THE BACKGROUND ARE SO VIVID...AND WE CAN?T SEE THE MAN'S FACE. THE HISTORY YOU'VE TOLD VERY INTERESTING. REGARDS FROM SPAIN AND GOOD LUCK.
