Imagine saving a single person’s life: you pass a burning building, kick the door down, rush through the smoke and flames, and drag a young child to safety. If you did that, it would stay with you for the rest of your life. If you saved several people’s lives—running into a burning building one week, rescuing someone from drowning the next week, and diving in front of a bullet the week after—you’d think your life was really special. You’d be in the news. You’d be a hero. But we can do far more than that.
