Usain St Leo "Lightning" Bolt (born 21 August 1986) is a Jamaican sprinter and currently the fastest human in the world. He is the first person to hold both the 100 metres and 200 metres world records since fully automatic time became mandatory. He also holds the world record as a part of the 4 × 100 metres relay. He is the reigning world and Olympic champion in these three events. Because of his unprecedented dominance and achievements in sprint competition, he is widely considered to be the greatest sprinter of all time.

Bolt was born on 21 August 1986 in Sherwood Content, a small town in Trelawny, Jamaica, and grew up with parents Wellesley and Jennifer Bolt, his brother Sadiki, and his sister, Sherine. His parents ran the local grocery store in the rural area, and Bolt spent his time playing cricket and football in the street with his brother, later saying, "When I was young, I didn't really think about anything other than sports".
