Interesting idea.  So if we believe in the addaptation theory, Bennet's
rats might have addapted during their first dive and shown false 'improvements'
on subsequent dives with asprin.  Hard to argue that without looking at
his experiment, which he didn't write up in the paper.

Interesting post RE: taking a day off to avoid a 'rebound' narcosis sensitivity.

Although numerous mech could be envisaged, it is hard to propose one that would
show
such a large delay.

Also, taking a day off following acclimatization would/does have the effect of
abolishing
acclimatization.

Is indeed the post hiatus dives as 'narcosis' free as the pre-hiatus ones?
Also, fatigue being intimately linked with IGN, is that an explanation for the
putative de-acclimatization or resensitization.

Comments appreciated

Esat
