Thanks. I'm not a firm believer in "proof" of any kind - just increasing
degrees of convincing evidence (science is among the most convincing lines
of evidence for people who think in terms of logic).  Actually, it was
closer to 8 atm of O2 (7.7 atm) - and I didn't learn much from the
incident (it takes far greater repetition of anecdote before I try to
extract meaningful information).  The most remarkable and potentially
insightful thing for me was the level of narcosis - not all that different
from air at the same depth (very subjective, I agree; and also influenced
by the placebo effect, which I completely agree applies to many things).

Incidently, I have to agree with Tony - there is something more to the 
post-air-dive-excessive-tiredness thing than simple physical exertion and 
placebo effects.  In fact, I had to overcome the presumption that the 
fatigue was due only to physical exertion/thermal drain - it took a 
couple thousand dives before I finally realized there was something more 
to it.

Aloha,
Rich

P.S. I wish I was 19 again too - then I would do things a little 
different on that aprticular day, and perhaps not have so much scar 
tissue on my spinal cord! :-)
