Ananova:

A 105-year-old man is to make a challenge on the world record for the 100 metre sprint for centenarians.

Guo Cairu, of Nanjing city, Jiangsu province, has just been chosen as torch runner for the upcoming 10th National Games, reports Dahe Daily.

The current centenarians' 100 metre record is held by South African Philip Babinowitz with a time of 30.86 seconds.

He became the world's fastest 100-year-old last July when he slashed more than five seconds off the previous record.
