Edward Nino Hernández is in many ways a typical 24-year-old Colombian man. He loves to dance reggaeton, dreams of owning a car – preferably a Mercedes-Benz and wants to see the world. What sets him apart is his size. He is slightly taller than a piece of carry-on luggage and weighs just 10kg (22lbs). Nino Hernández has just been officially certified as the world's shortest living man by Guinness World Records, measuring 70cm (27in). "He hasn't grown since he was two years old," his mother, Noemi Hernández, said of the oldest of her five children.

"They never gave us a diagnosis," says his mother, during an interview in the family's sparely furnished apartment in Bosa, a district of southern Bogotá.

Hernández, 43, said her son weighed 1.5kg at birth and was 38cm long.

She said doctors at the National University studied him until he was three, then lost interest. She and her husband, a security guard, lost a daughter who was similarly small in 1992 when she was nearly a year old.

The couple's youngest child, 11-year-old Miguel Angel, stands 93cm tall and has facial features similar to his older silbling. The other three boys are of average height and appearance.
