You all seem to forget that when the internal pressure of the respiratory system is equal to the barometric pressure of the ambient pressure of the atmosphere the cranium will neither expand nor contract. This is on of the first rules they teach you when you get your SDI certification. However I understand that many of you are PADI (put another dollar in) certified and this was not covered in those lower level classes.

(Looks like "bait" to me!) Yet a response in like kind seems approriate.

The substance of this diatribe affects the olfactory synapses in a manner similiar to biotic ejecta produced by the degeneration of organic matter in the gastrointestinal tracts of male bovine specimens. However, it is to be noted that some individuals retain an atypical amount of this material, to the point that they near one hundred percent capacity.

(Translation for those in a hurry: "The statement smells like BS, and some folks are just FULL of it!")

meant in fun only...


:D
