I live across the street from the beach and we have several plunges every year. I have not engaged in such behavior, despite the layer of fat I have built up over my 56 years. I think due to the shock, I might succumb to a heart attack, not the manner I would like to exit.
Good for those who are younger at heart than I.. Best to you and your research!!
