Who’s your life saver???
a lifesaver, ie something to help you float in the water, originally was a circle with a hole in the middle, hence the shape of the candy
Life Savers were invented in 1912 by Clarence Crane, a Cleveland chocolate maker who wanted a sweet product that wouldn’t melt in the summer heat. He decided on a peppermint hard candy in the shape of a circle with a hole in the middle. Since the mints looked like miniature life preservers, he called them Life Savers and registered the trademark.
Hole is to leave an open airway for possible choking
