Voltaire (and later Peter Parker's Uncle Ben) once said, "With great power comes great responsibility."
Well there's no arguing: Athletes have great power. It comes not only in the form of physical skill, but also mental acuity, and influence over an admiring public.
The amazing athletes and sports figures on this list all used their power—in one form or another—to save the life of another human being. Some indirectly. Some very, very directly.
Not all the tales are happy; some on this list sacrificed their future well-being, or even their own life in order to save another.
But all the tales are deeply inspiring. And all will make you proud of the courage and selflessness of the world's athletic community.
Meet 20 athletes. Meet 20 heroes.
