<He's an engineer whose world is driven by rationality -- logic and method dictating action. That's one reason he likes diving. He pays attention to the smallest details. On this day, besides his underwater camera and slate, he snapped a whistle to his wet suit and carried a yellow-green neon safety tube that can be inflated as both a marker and a flotation device.
He had never needed the safety equipment. But years of instruction had drilled into his head: Always carry it. >>
You know, for an engineer who "cuts imposing figure," and "pays attention to the smallest of details" he sure is coming off like an idiot.
