This young man is setting out to look for water. It can take a long time to find it, and he may have to walk a long distance. Then the trip back home with the weight of the water suspended from the cloth on his head.

He may carry 2 or 3 at one time! (Pretty sure I couldn't manage ONE!)

I have seen them walking.....bent over and holding their head with both hands so that their neck can support the burden.
