The number one ranked tennis player in the world, Novak Djokovic, is a skier. He's not just your one-weekend-a-year in Aspen style skier either. Djokovic first started to ski at the age of 2 at Kopaonik, a resort in his home country Serbia. Sure, he lost the final of the French Open over the weekend, but he beat Rafael Nadal and Andy Murray in style to get there. Using skiing as cross training appears to be a key reason for Djokovic’s success on the tennis court where his trademark style includes sliding across the court and hitting from awkward positions. The Wall Street Journal even compares him to legendary American ski racer Bode Miller.

When he was around 10 years old, Djokovic had to decide between tennis and skiing. Obviously his decision to pursue tennis has worked out well, but one can't help but wonder where he'd be if he had stuck with skiing. Would he be winning the Hahnenkamm downhill or perhaps shredding Alaskan faces in the next film from TGR?
