Nothing is as natural as breathing, but for those of us who dive, our most memorable breath was probably the first one we took underwater through a scuba regulator. This month's covers and the feature article titled "Diving Firsts: Viewing the World Through a Dive Mask" illustrate that if you're like most divers, that one breath likely changed the way you view the world.
