A very good story about ultra-deep cave diving from Outside Magazine:

Raising the dead

"At the bottom of the biggest underwater cave in the world, diving deeper than almost anyone had ever gone, Dave Shaw found the body of a young man who had disappeared ten years earlier. What happened after Shaw promised to go back is nearly unbelievable—unless you believe in ghosts."

This got me interested in diving and decompression sicknesss, and I found these two articles:

• Here then is my decompression illness story
  
  
• Nitrox Scuba Diving

The first article shows what can happen when you get even a mild case of decompression sicknesss. The second one has a nice explanation of the process.
