In front of the grave of the founder of spiritism, visitors have been repeating one gesture for more than a century. What is it?
The answer
On Allan Kardec's grave, the back of the bust's neck has been polished smooth by hands. Tradition holds that one makes a wish while touching it; the City has repeatedly pointed out that the gesture damages the bronze. Year after year, it remains the most flower-covered grave in the cemetery.
