Every four years, millions of people are captivated by curling, a sport in which stones are rolled across an ice rink, attempting to land them in the center of a target about 45 meters away, knocking the opposing team's stones out of the way. Social media is flooded with people imitating the athletes' movements and analyzing plays. The Sweden-Canada match ended in a heated exchange as the Swedes accused their opponents of cheating, with millions of users trying to determine who was right. Every four years, curling shines. "The Olympic Games are an opportunity for people to take the plunge and, after seeing it on television, be encouraged to try it," explains Carles de Moxó, president of Curling Puigcerdà, one of the clubs in Catalonia. Many people don't know it, but curling is also played here.
