Don, go to the UHMS and read studies until your eyes fall out. The
German's have a great one.

I think you might want to ask why the guys who hold all the records in
cave diving , who have the best track record in diving, and who have
been doing it longest think the way they do. Do you think that maybe I
am just a pussy? A wimp who can not "handle" air at 150 ( I can't, by
the way)? Do you thihk that even though I have a degree in math and work
on Wall $treet that I am too stupid to dive air, but that some of these
insect level dive instructors have more grey mattter and higher IQ's
than I do? Do you think that guys in the WKPP like Bill Mee ( biomedical
engineer) or John Rose ( PhD in math ) or Scott Landon ( chemical
engineer for the DuPont Company) are not bright guys like Tom Mount or
his instructors and so can not "handle" air?

You then might want to ask what if anything ever have any of the air
strokes done.

You might also want to look at the whole picture, like that fact that
the nitrogen causes damage, that there is no way to successfully
decompress from air, that there is no way to do an air dive without
subclinical DCS symptoms, that commercial diving does not use it, and
that the reason it is so tenaciously clung to is the fear of admitting
the horrible mistake being made combined with the money being taken for
nothing by the training agencies.

You might also want to ask why the obvious needs to be spelled out . Let
me give you an example. 50-90% of what goes through my wife's embergency
room has drugs or alcholol attached to it someplace, and I have yet to
see any study that points this out. Another friend of mine who runs
another ER cites the same percentages, especially when it comes to auto
accidents, fights , gun shots, and other "accidents".

Guess what - neither of them drink and drive. Gee, I wonder why? Don,
how many people have been killed air diving? How many have been killed
where there is no good explanation, yet they were between 100 and 170 on
air?

How many more will go that way? How can smart people get their lead from
dumb boat monkey dive industry mutants?
