A couple thoughts about this:

1)  Some people do not understand that Nitrogen
narcosis can ruin your day (and your life), and the
narcosis can vary from day to day, and dive to dive,
in the same diver.  Throw in CO2 buildup at depth
from an unexpected problem, and you multiply the
narcosis even more.  Sure you can build up a certain
amount of tolerance by repeated exposures, but the
effect still can be quite variable, and deadly.

2)  There is a "machismo" factor involved in deep
air diving.  Many people think it is cool to go
deep on air, and some like to brag about how deep
they've been.  If you think it can't kill you, or
you think you are above the laws of human physiology,
you are wrong.  It might be helpful to check out this
link from the Aquacorps archives, to see what some of
our more experienced predecessors had to say.  Check
out "Beyond Machismo" for some good thoughts:
