Have your attitudes about bathrooms changed as a result of doing FLUSH? What was most surprising thing you learned?

I’m much more conscious of bathrooms now. Seeing what some people have done with their bathrooms has amazed and delighted me. I’ve also been struck by how slow technological change has come to bathrooms. It’s a thrill to see and hear about new efforts being made to improve bathrooms (and extend access to them) all over the world. But it seems the obstacles to more effective human waste disposal are as much cultural as technological.
