RIO DE JANEIRO, BRAZIL - AUGUST 01: Olympic refugee team swimmer Yusra Mardini trains at the Olympic Aquatics Stadium ahead of the Rio 2016 Olympic Games on July 28, 2016 in Rio de Janeiro, Brazil. Mardini is a refugee of war-torn Syria. She survived part of the dangerous journey, from the Turkish coast across the Aegean Sea to Greece, swimming to help ferry an overloaded inflatable dinghy across open waters as most other passengers could not swim. The International Olympic Committee will for the first time have a team made up of stateless refugees. (Photo by Clive Rose/Getty Images)
