In 1999, both of skydiver Joan Murray's parachutes malfunctioned, leaving her to free-fall 14,500 feet above North Carolina.
Miraculously, Murray survived, thanks to the fact that she landed directly on a mound of fire ants.
Doctors believe that the intense shock of being stung over 200 times by the ants released a surge of adrenaline, which kept her heart beating.
