You Start swimming like you have never swam before. You surface and start doing a front stroke as fast as you can.

The short line is drawing closer, fantastic, except there is one huge mother of a fin circling you. Regardless you press on, when you feel the massive jaws of the great white clamp down on your torso, you scream...well...gargle as it drags you back out to sea. It lets you go, the water is red, you are seriously hurt.

The shark seems momentarily to be a distant memory as you float in what seems like purgatory. You float to the surface...the world goes white.....
