It marks the second consecutive gold medal in the Olympic Games for Bolt, and it should mean that he will be attending the 2016 Rio de Janeiro Games in an attempt to win his third in as many competitions.
Bolt will only be 29 years old by the time the 31st Olympiad rolls around, meaning he is likely to have something left in the tank four years from now.
For Bolt to call it a career and not return to the Olympic Games would be nothing short of a crime. He would be depriving the world of the "Usain Bolt Show," which is one of the main draws in the track and field portion of the Games. He would also be depriving himself of a huge shot at another gold medal.
Even if Bolt is a step behind in four years, he would still be able to hang with the pack. He's blown away the field in the last two years, high-stepping to the finish with sheer elation on his face in back-to-back Games.
He is the cream of the crop among sprinters.
We would be lost without Bolt in the Olympic Games. Not only is he one of the best at his craft on the track, he's a master performer away from it. He finds the perfect way to connect with his fans and ensure that they tune in to see him race. He loves the attention and relishes in the spotlight.
He has hit the genetic lottery in the sense that his body is perfect for sprinting. At 6'5" tall, he is the LeBron James of his sport. There is no competitor that can match his combination of size and speed.
His long strides don't let him get off to as fast a start as some of the field, but he's impossible to keep up with when he gets started. That much was obvious in his most recent gold medal sprint, as he hung with the pack at the beginning of the race, then pulled away gracefully to win handily.
There have been no signs of Bolt falling off at all. Of course, he's still in the prime of his career at 25 years old, but there isn't reason to believe that he won't be able to keep it up.
Bolt hasn't made it known whether he will call it quits after these Olympic Games or return to complete the trifecta, but given his age and sustained dominance, signs point to him being able to return and emerge victorious again.
