10 facts about Usain Bolt that you probably didn't know

#6 He was born with a rare spine disorder

Bolt was born with scoliosis, which is an abnormal curvature of the spinal cord.

“When I was younger it wasn’t really a problem,” he told ESPN magazine in 2011. “But you grow old and it gets worse. I don’t have to worry about it as long as I work hard.
