ROME - Sometimes the universe has a way of telling you something.
An Italian caver was rescued after being stuck underground for four days -- the second time in 18 months she has had to be carried out of the same cave.
Rescue teams used mini explosives and stretchered Ottavia Piana out of the narrow cave system in northern Italy after she fractured several bones in a fall.
"We know each other," Piana told Doctor Leonardo Sattin as he treated her far below ground during the epic operation.
He had also helped drag her out of the same cave when she broke a leg there a year a half before.
