George, why don't you read the entire post. The study was real we did 
score what we did and if you read the conclusions it states that the 
threat of narcosis is real. It states one cannot respond to multitask 
functioning, it then gives a comparision to booze just to drive the 
point home.

It seems 90% of the peopole who reads this get the message that it is 
stating you do not develop a tolerance. What I refer to ad adaption is 
that you become used to the feeling of being imparied.  AND yes on a 
single function performance most anyone I know who dives deep can do 
it. They are still at high risk because they do not have a tolerance 
they have some limted behavioural modification. You know this from your 
own experience. I thought that using the example of people who were 
actively diving deep who really beleived they were tolerannt anf then 
showing the results that proved we could not respond to multitask 
problem solving really drove the point home that there is no true 
tolerance to narcosis. I went on to say that this study was the first 
to make me become respectful of narcosis. 

George, I'm showing real life data old or not it was factual and 
measurable and proved beyond the shadow of a doubt there is no 
tolerance to narcosis. Ther is an adaptation to feeling imparied and 
the ability to single focus ones mind on a specific objective. The data 
reflected clearly that when the s-- hits the fan the ability to respond 
is quite doubtful. I even used the if you arte in a cave or wreck it 
would be quite challenging if at all possible to reason your way out 
when imparied with narcosis.

WHAT is the problem you have with what I wrote if anything it supports 
your position. I use this in classes and all students digest it as 
showing the real problem and threat narcosis reflects towards a divers 
safety. You are the first I 'v seen that took it to mean one can handle 
narcosis.
