Recently, I was at the pool at the Boston Sports Clubs’ Watertown location when I overheard this exchange between a swimming instructor and a boy of 5 or 6.
Instructor: “You’ve just learned the dead man’s float. What’s great about that?”
Boy: “I don’t know.”
Instructor: “Well, if you get in difficulties, you’re on your back and you can breathe easily. You can then just float to the side of the pool or call for help.”
Boy: “What if I don’t have a cellphone?”
