 Well, it does to me. I mean, when I'm cave diving inside a water-filled space, I feel like I'm swimming in the veins of Mother Earth. I'm in the sustenance of the planet, that very drinking water that we draw up from the ground and use to supply humanity and agriculture and industry. It's like I'm in the very works of the planet. How did this get started for you? Was there a gateway cave dive, the one that got you hooked?
