On an "advanced" class dive many years ago, the instructor had us dive to the bottom at about 120 feet as fast as possible. It was very cold, and, as we reached the bottom, it became obvious that I had no idea what was going on. It was a nightmare and everything seemed very far away. My response time to everything was extremely slow. I have not been so severally narked before or since. If a real emergency had occurred, I don't think I could have dealt with it. This was a great lesson and really got my attention. If this was all I'd got from this class, it would have been well worth it. Narcosis is real, and a very bad thing to be avoided.
