Swimmers and the Choking Reflex

Has anyone noticed that swimmers have excellent control of their choking reflexes? It is inevitable that swimmers will breath water on occasion. During freestyle, for example, I sure we have all exhaled in preparation for another breath when a wave crashes into our mouths causing the first part of the inhale to be all water. At this point we have two options: (1) We can stop swimming, make gagging sounds that echo throughout the pool area, and act as if we just had a brush with death, OR (2) We can calmly turn our heads back into the water, use whatever air remains in our lungs to casually cough out the water, and continue swimming as if nothing happened. Of course, this ability to casually brush off breathing water only comes with significant experience in the water, something only swimmers can brag about. Based upon this, you now have an answer to the following question: Besides great physical ability, a strong heart, a killer physique, an enjoyable hour at the gym, engaging competitions, and good camaraderie, what has swimming ever done for you? Excellent control over the choking reflex, of course.
