I read sometime back, most likely in "Prevention" magazine which I was reading religiously at the time that those with a diet higher in fiber tend to have softer stools, while those eating a more concentrated diet, usually high in animal protein tend more to shit stones (which also tend to clog toilets). Whatever the piece I read was, it also said that the stools of the higher fiber-eating people tends to make better fertilizer.

Apparently, Mother Earth, in her infinite wisdom has "intelligently designed" a cycle where we eat less meats and concentrated foods, and we produce better fertilizer to help grow more of the things we should be eating anyway. Makes sense to me.

As to the original subject of this thread, a stream of water or a damp cloth will work wonders.
