Is there any truth to the story that they're called "life savers" both because of their resemblance to a flotation ring like those found on ships, and because the hole in the middle would keep a child from choking on one?
"Life Savers is an American brand of ring-shaped mints and fruit-flavored hard candy. The candy is known for its distinctive packaging, coming in aluminum foil rolls of eleven pieces.
In 1912, chocolate manufacturer Clarence Crane (Cleveland, Ohio) invented Life Savers as a "summer candy" that could withstand heat better than chocolate. Since the mints looked like miniature life preservers, he called them Life Savers."
