My heart only raced for so long each time I went down into the cage because I had to come up for air. Coming up for air involved climbing back up the grid of the cage like a ladder, which didn't seem too safe when I was a little disoriented with the lack of buoyancy; often times, my arms would go through the grid, right into the chomping zone. Fortunately for me, I kept my limbs intact; fortunately for the diving company, I had signed my life away on a release form anyway.
In the end, shark cage diving is something to experience for any thrill seeker. If you think Shark Week on television is exciting, you might like facing your fear in the water (as long as you're in a protective cage). Just make sure that, as with any thrill ride, you keep your arms and legs inside at all times.
