This is our Cuenca mystery…We came upon this man in the street market with a lime, a skeleton and an anatomically correct plastic model of human internal organs. He took the lime and moved it gradually down the dummy, from the mouth through the esophagus then down again through the intestinal tract while vigorously explaining some unknown thing to the intense listeners. All of it was in Spanish which only heightened the mystery for us. As we walked on he was pointing at the skeleton and a display board still talking. Was he selling limes, a hard sell for citrus? We’ll never know.

Hello Jill and Dana,
Very interesting mystery!!!!!
I looked it up and they said it can be used for prevention of decay and spreading of disease.
They also use it on dead bodies to speed up decomposition.
Who knows???????
Cheers😎😍
Maybe so. His table was covered with books so whatever it was he had plenty of documentation.
