See if you can hold it as long as this guy does

This unnamed diver goes down 65 feet to the ocean’s floor and walks around hunting fish like he was walking on dry land.  Try to hold your breathe while you sit there watching this video.  Now imagine how it would be if you were actually exerting yourself physically.  This video is only 2 1/2 minutes long and he can do this for 5 minutes at a time.
