Swimming with Icebergs by National Geographic - Man free dives in and around floating icebergs

The crux of the video is how the swimmer can lower their pulse rate at a moments notice. It is known as mammalian response. Our bodies are designed to lower our blood pressure when our faces get submerged in water. Nonetheless I just enjoy the swimming.  No wonder swimming is a great sport for those with high blood pressure.
