From Buzzfeed: This video of world champion freediver Guillaume Nery’s special dive at Dean’s Blue Hole is stunning. It’s filmed entirely on breath hold by the French champion Julie Gautier and I feel like I am out of breath every time I watch this.

This is amazing to watch. I would be freaking out. As it turns out, Deans Blue hole is the largest underwater sinkhole in the world, almost 700 feet deep, in the Bahamas.
