Two of the world's most followed on social media — Britain's Prince Harry and Canadian Prime Minister Justin Trudeau — are counting down to the 2017 Invictus Games, a sports competition for wounded and sick service personnel. Inspired by a visit to the Warrior Games in the United States, Prince Harry founded the Invictus Games in 2013. On Monday, the prince said he's been told that Toronto's Paralympic-style competition will be the largest and best so far. The Invictus Games were originally held in London in 2014 and included more than 400 competitors from 13 countries.
