Usain Bolt’s 100m world record is the longest-standing in history

The Jamaican has surpassed Jim Hines, who was the first man to break 10 and who held the world record from 1968 to 1982

Usain Bolt “not worried” about his world records being broken

Bolt’s 100m and 200m world records have stood for 14 years

Jim Hines, the first man to run the 100m in under 10 seconds, dies at 76

Hines won the 100m at the 1968 Olympics in Mexico City and held the 100m world record for nearly 15 years
