I will always believe what I please.  But what I believe depends on a lot 
of factors, including knowing the source of a tidbit that I am told.  
Besides, just because I don't dive deep on air doesn't mean that I don't 
want to understand hyperbaric physiology.

O.K. -thanks for clearing that up.  I had thought you said the "Chinese" 
were the ones with the rigid RBC's.

Now, I'm no chemist - but isn't this the complement system (or part of 
it, anyway)?  I agree that the fluelike symptoms an fatigue are 
likely ultimately a result of microcirculatory damage; but my experience 
tells me that these happen more in response to fast deep ascents 
(regardless of bottom gas), than to breathing high PN2.  In other words, 
a bubble-growth thing rather than a rigid RBC thing.

O.K.
