    My uninformed two cents worth...
    I wonder if the bends and nitrogen narcosis for divers with large air
    supplies (either hard hat or aqua lung) are not caused by not caused by the
    large volume of air they are exposed to under high pressure over
    time.  Stated another way, if all of the air in an animals lungs (one
    volume) were to go into solution in the blood would that be enough to cause
    narcosis and bends?   Or would it require many lungs full?
