Zara Hartshorn, 13-year old from Rotherham, England

Zara Hartshorn from Rotherham, England is only 13-year old, but she’s already looks at least 50.

“People call me ‘granny’ and ‘monkey,’ ” she told the New York Post in a recent interview.

“Sometimes I’ll just go into the toilet and cry.”

Hartshorn suffers from a rare genetic disease known as lipodystrophy. The disease causes layers of fatty tissue under the surface of the skin to disappear.

It is reported only around 2,000 people in the world are said to have the condition, and there is currently no known cure.

“Lipodystrophy is genetic disorder in most cases. It’s very very rare,” says Dr Jeanine Downie a Dermatologist.

“80 percent of the cases in women typically develop before the age of 15.”
