I took the longest showers of my life after every time I visited Gramacho. It affects the personality of the catadores. They always dress really well, they're very sharp, and when they go out they always wear a lot of perfume because they're very conscious of the possibility of having the smell.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.
