I completely disagree. After over 50 dives to the Monitor at 235 on air, I can tell you this about narcosis and moi. One year, I had a range of experiences from "unaffected" to "completely stupid" on different dives. On day one of ten days of diving I experienced the greatest narcosis. I became less affected by narcosis on suceeding days. By day three there is hardly any noticable effect of N2. Days 4,5,6 ditto day 3. On day 7 I became completely stupid. Days 8,9,10 unaffected. Different effects on different days, same dive, same air, IQ=49. Other years follow the same general pattern. Sometimes I notice a lot other times I don't. Banning diving to people with low IQs would wipe out the industry as we know it today. Then there would be only diving via techdiver lists, etc. like some do today.
