Sure I like adrenaline.

When I scuba dive at night at 80 feet or so I like to kill my lights turn upside down and float weightless just hearing myself breath slowly, totally relaxed, looking at that tiny light from the boat above.

Sometimes it feels like something big is about to come out of the darkness at any second and make you its dinner and no one will ever hear you or know what happened to you. What a rush. Ive also removed my mask at 80 feet in the dark and cleared it back out. Keeps me prepared to manage a panic situation should it occur.

Ive also dropped my tanks, and weight belt at 80 feet and took one last deep breath and made an accent to the surface with only a breath of a air. YOu have to put yourself in a trance state of calm. Takes about 2-2 1/2 minutes to accent. For nitrogen reasons you cant accend faster than the smallest of the bubbles you are slowly exhaling, that is your accent speedometer. You are always aware of panic and learn to manage it and have control over it. But quite the adreniline rush.
