This man descend 20meters (65feet) to sea floor, hearts slows down to 30beats per minute, squezzes its lung to 1/3 of its initial volume, even without weights he is negatively bouyant enough to strive across the bottom of the sea as if like hunting on land, 2 1/2 minutes of hunting under pressure. He can still manage to stay as long as 5 minutes! - indeed a man from the Badjao tribe has the potential to win our country a gold medal in the olympic Panda-
