Winston Churchill used to tell the story of a British family that went out for a picnic by a lake. In the course of the afternoon the five year old son fell into the water. Unfortunately none of the adults could swim and as the child was bobbing up and down and everyone on the shore was dissolving in panic, a passerby saw the tragedy of the situation.
At great risk to himself he dived in, fully clothed, and managed to reach the child just before he went under for the third time.
