I read somewhere (probably FR) that in India, they’ve finally begun to convince people to use indoor plumbing. They were told that it would help health, but still didn’t do it.
What changed things, was the women were tired of running the risk of being molested every time they went outdoors to do their duty. When they finally saw the safety aspect of indoor plumbing, they started using it. Of course, once you get used to it, going outdoors quickly loses its appeal. There’s a lot to be said for comfort and safety, not to mention, convenience. ( I’ve done my share of camping.)
Wouldn’t it be great if hand soap becomes the norm in these countries?
