yeah it all comes together... and adds up to what i call "mental stamina",
might say "sensory adatpation" contributes as well...

on decent lets say "all-of-the-above" contributes to the narcosis, upon
reaching the buzz one either accepts it and realizes he\she will live and
goes on with the dive thus overcoming the "mind killer" fear... at this
point the narc is in the background and the diver concentrates on the
goal of the dive (hopefully any diver at this depth *will* have a goal
in mind):  walaha, mental stamina prevails.

or:  the diver thinks about all the things that *might* go wrong; air
supply, reg malfunction, black out, large hungry fish, ufo's that want
to take someone back to thier planet, their sister ending up with their
new porsche if they don't get back to the boat...   you get the picture,
and the narc grows... EXPOTENTIALLY. (physology: increased respiration,
adrenalin and co2.. opnions here please, on what, if any, affect these
combined may have)  

i agree with everyone that "you get what you expect", and the more you
experience the effect of narcosis the more you *learn* to deal with it,
this is not saying that you physologically adapt, i'm not sure on that
one yet.  i think there are too many if's in that area, and too many
factors that change from day to day and from diver to diver...

whew..

lastly on the subject of mental stamnia... "argue for your limitations

and they will become yours"

sea ya,

dennis
