This video is a must see for prolonged smother enthusiasts, as Rebekah tests out her theory about the Dive Reflex and its application to facesitting, using her willing volunteer Robert. The dive reflex causes any person who feels water splashed on their face to be able to hold their breath for longer than they usually could... It is a physiological response to the stimulus of water hitting the face which simulates the human body diving into water, causing the heart rate to slow and the body's oxygen supply to be directed to the body's vital organs.

DON'T try this at home, folks... Robert is a trained athlete and very proficient at breath play. (Duration 30m15s)
