gregory grit his teeth , took a deep breath , and jumped : the wind whooshed in his ears : he kicked hard with his feet as his stomach rose to his mouth : he hit the water hard and sank like a stone : the rush of crashing liquid replaced the sound of the wind : the chill shocked : he inhaled water , choked , lungs flaring with pain : his feet touched the pools bottom : he pushed off and kicked for the surface : his head broke the surface , and he drew deep , painful breaths .
