 Underwater when I'm working, I feel good. I feel like it's just a way for me to get to work. But at the same time, you have a lot of other things you got to worry about. I have to worry about how much air do I have left. I got to worry about my buddy, you know, because he's watching me and I'm watching him making sure we're okay. And if we're lucky, we get to see. If not, everything is by feel. You always have a buddy with you. You're never doing anything by yourself. You're never alone.
