The average age on that poll is way higher than what I see here on Guam, where there is large military population with a large disposable income, many of whom live on a peninsular Naval base that is surrounded by some of the best diving spots on the island. And Palau, Chuuk, Yap, Kosrae, Pohnpei, Cairns, Manila, etc are all direct flights. I would guess that the average age of people walking around the LDS is upper 20s to lower 30s, with a lot of people who clearly enlisted right of high school and were shipped off to Guam, though my group of regular divers skews older due to some old fogies messing up the average.
