She barely eats, sleeps and doesn't feel pain leading doctors to dub her the 'bionic' girl.
Olivia Farnsworth baffled doctors when she was hit by car and dragged down the street but walked away without shedding a tear.
The seven-year-old, who often goes up to three days and nights without sleeping, has a condition is described as chromosome 6 deletion.
She is believed to be he only person in the world to exhibit the three symptoms together.
Mother, Niki Trepak, 32, from Huddersfield said the condition meant her daughter had 'no sense of danger.'
'She got run over and dragged down the street by a car and she didn't complain,' she said.
'She was dragged about ten car lengths down the road. It was horrendous, I don't think it's something I will ever get over.
'I was screaming and all my other children were screaming as she ran out.
'But Olivia was just like, ''What's going on?''. She just got up and started walking back to me.
'Because of the impact she should have had severe injuries. She had a tyre mark on her chest. But her only injuries were she had no skin on her toe or her hip.
'The doctors think what saved her from injury was she didn't tense up.'
The mother-of-five said the signs of Olivia's condition started when she was just a few months old.
Ms Trepak said Olivia never cried as a baby and stopped sleeping in the day from the age of nine months.
The condition also meant her hair did not grow properly until she was four-years-old.
'She became a really fussy eater and would have nothing but milk shakes. At the moment it's chicken noodles,' she said.
