Huh?
Could someone please explain this?  This is the second time I've heard
reference to air being less narcotic than nitrox.  (George Irvine made
mention of it saying that air was less narcotic than 30% at 130')  This
goes against everything I learned and goes against what seems to me to
be intutitivly obvious; ie: less PP N2 = less narcotic effect.  I must
have missed the thread discussing this, or maybe I'm missing something
real basic.  Anyway, being an average NE wreck diver (70 - 130 FSW) and
generally breathing Nitrox on these dives, I'm curious as to what the
thinking is here.  Just trying to learn.
