As might be expected, this decision initially aggravated the problem of inefficiency. There was the bungling associated with a new endeavor, and there was the exhaustion brought on by over-watching the films of Jacques Cousteau. And yet, once I’d completed advanced scuba training and a Fish Identification Course and I began to dive properly and in fact at every opportunity, I learned that the undersea world may be nearly a pure substitute for the world from which one enters it. I cannot help pointing out that this substitution has the effect of limiting what might be termed the biographical import of life—the momentousness to which one’s every drawing of breath seems damned. To be, almost without metaphor, a fish in water: what liberation. I loved to dive at Musandam. Without fail my buddy was Ollie Christakos, who is from Cootamundra, Australia. One morning, out by one of the islands, we followed a wall at a depth of forty feet. At the tip of the island were strong currents, and once we had passed through these I looked up and saw an immense moth, it seemed for a moment, hurrying in the open water above.
