What you *said* was that you had been lucky so far.  Not that you had
been bent and not gone to a chamber.  A few months ago I crashed my car
and wrote it off.  Are you saying that becuase the police weren't called
and there is no official report, that it didn't happen?  Is "I've been
lucky so far with driving" a fair comment?

I don't deny DCI in ANY WAY.  So "ALL OF US deny DCI in some way" is not
correct.

I haven't got any stats on how many people of different races go home and
don't tell anyone they have been hurt, but if you are interested in the
culture of the American diver then reading Dr. Jennifer Hunt's papers will
be most enlightening.  (Montclair State University)
This culture is of concern to most divers, as the American training
organisations have a very strong influence on diving throughout the
world, particularly in Australia where the only Ozzie training
organisation (FAUI) which taught decompression diving right from ab initio
training has been swamped by the PADI NAUI SSI IANTD ANDI NASDS flood so
much so that most Ozzie divers not only don't know how to do deco diving,
but refuse to believe that it has ever been taught.  The fact that
Queensland has adopted the American limits rather than the Australian ones
should be enough to show what a strong influence they have on us.
If I sound mad that's because I am.  You remember the fiasco where you
recommended I dive on the OzPlay boat.  I had a FAUI Scuba diver cert,
I'd been trained to do dives to any depth that I could tolerate, and how
to recoginise when I had reached my personal air diving limits.   And
this clown won't take me out to do a dive in 50 m becuase I don't have a
PADDY Deep card!!!!!!!!!!!!!!!!!!!!!!
American, fear of litigation driven, training has already affected my
diving directly.
If anyone is interested I can expand on this point *greatly* but I've
raved enough for one post.

PS, I conducted a survey before, without much of a response.  One
very interesting thing was a bare faced *lie* from someone connected
with a technical training organisation that dramatically understated
DCI hits.  He claimed *ZERO* DCI amoungst his group of divers when I know
for a fact he has been hit himself! and accompanied a diver to the
chamber.
