You've seen the Polar Plunges before, right? You know, usually on New Year's Day, a group of people jump into icy ocean waters as a way of welcoming in the new year, thus attracting lots of media attention.
The tradition goes back to 1903, when Bernarr Macfadden founded the Coney Island Polar Bear Club. He was referred to as the "Father of Physical Culture" due to the fact that he was an early advocate of physical fitness, natural foods and physical exercise.
Macfadden espoused that "[o]ur bodies are our most glorious possessions, that health-wealth is our greatest asset ... that weakness is truly a crime ... that every man can be a vigorous vital specimen of masculinity: that every woman can be a splendidly strong, well poised specimen of femininity." The Polar Bears, as you may know, are famous for their plunge into the icy New Year's Day waters off New York's Coney Island.
