A condition called congenital analgesia, characterized by
decrease or complete absence of pain sensitivity, not

diagnosed her with a fracture and began his treatment. According to scientists,
Now the Marsili family is undergoing experiments that
remind torture. Italians are pricked with needles, excessively

everything like that.
People of science have already determined that these relatives are present.
