According to a recent study made by the BMC Emergency Medicine, Geneva, the frequency of emergency calls in the Swiss city decreases when Roger Federer is playing tennis matches. Some experts led a study made from May 2013 to August 2017.
In average, when Federer plays tennis around the world, there are 10% less calls. The researchers studied the number of emergencies during the French Open, Wimbledon and ATP Finals men's semifinals and finals matches. 7% average calls less during a semifinal.
15% during a final. In 40% of the finals, and 46% of the semis, a Swiss player - sometimes Wawrinka, often Federer - competed. They also found that when you are a fan of Roger or Stan, you are also a tennis fan in general. Nadal or Djokovic are great for your health too.
How can it be explained? They suggest that some calls were "simply avoided" because they first want to know who will win. The health can wait. Source: Le Matin.
