Hey Hugo,

This is a public forum and your going to get people
who both agree and disagree with you. I happen to
disagree with you. Deep air is not a good idea. People
dive it, most people get away with it. This does not
mean that this is the best option.

You can have a few drinks.  Does this mean you are
impared? Where do you draw the line?  Deep air is the
same thing.

If you dive deep on air you are impared. Sure you can
get away with it most of the time, but don't come on
this list and try to justify it as being OK and tell
people you are going to save the masses by bringing
the "wisom" of deep air to the people!  Just admit
that deep air is not ideal. Say you plan to work
towards something better and be done with it. Stop
trying to justify deep air!

Mat.
