Here’s a tip for people that are swimming on the beach and gets approached by a shark. Do the exact same thing as you would if you were being approached by a bear… play dead. Just go underwater a few feet and hold your breath for about ten minutes. Eventually the curious shark will assume you’re no longer alive if you’re under for that long and it will leave the area. After it’s gone, surface and then quickly swim to shore. I sent my suggestion to the U.S. Navy, and they sent me a list of several local mental health institutions in my area that they felt I should contact, without an explanation for their recommendations. Weird.
