Pride in Korean unity

Late South Africa president Nelson Mandela once said: "Sport has the power to change the world" - a maxim that has become enshrined in textbooks and documentaries around the globe.

Having heard so many inspiring sports stories in my career, I truly believe the power of sport is strong enough to heal wounds, warm hearts and overcome setbacks. But what I am experiencing at the 2018 Pyeongchang Winter Olympics has made me realize I still underestimate it.

When the joint delegations of the host Republic of Korea and its northern neighbor, the Democratic People's Republic of Korea, marched in Friday's opening ceremony of the Games, it felt like the entire stadium was wrapped in a warm glow of unity ... which made the freezing winter night less unbearable.
