Usain Bolt

Sprinter Usain Bolt adopts a cheetah The fastest man on Earth, Usain Bolt, has adopted the fastest animal on four legs, a cheetah, and has given it the only suitable name - Lightning Bolt. The champion sprinter, on a four-day trip to Kenya, looked nervous as he was handed the three-month-old cub - which is about the size of a household cat. But he soon recovered his composure to name the cub in his honour. The Jamaican sprinter is helping to launch a conservation campaign run by German charity the Zeitz Foundation.
