In light of Nelson Mandela's death and the significance of social media today, people are taking to Twitter to express their condolences.
Mandela was known to be a fan of sports and was an amateur boxer in his younger years. He believed sports "had the power to change the world."
"It has the power to inspire. It has the power to unite people in a way that little else does. It speaks to youth in a language they understand. Sport can create hope where once there was only despair. It is more powerful than government in breaking down racial barriers."
Athletes have been expressing their condolences since hearing of Mandela's death.
