Dozenes of rivers crosses Bali from North to South. Many people still having their daily shower in the rivers... Also they wash their clothes at the same time.
Any object can be carried over their heads...from the grass for the animals, wood for the fire or a gallon of gas for the kitchen. Specially women are really impressive to see. Looks like if they don't do a big efford. I would not like to try. One of my favorites subjects.
