There's so much inspiring in this article that it's difficult to pick out just one example to share here. But this seems appropriate.
In 2014, Elizabeth Marks, a former U.S. Army sergeant, was traveling to the United Kingdom to compete in swimming events at the inaugural Invictus Games when she went into respiratory distress and nearly died. She was airlifted to a hospital in England, where medical staff saved her life. This year, Marks was able to compete in the 2016 Invictus Games in Orlando, Florida, and when Prince Harry, who founded the games, hung yet another gold medal around her neck, she promptly returned it to him, asking him to give it to the hospital staff members who saved her life two years ago.
