        Hello Dennis,
  Interesting, most do in fact think in terms of words, often
"hearing" them.
        [snip]
  Tell that to a blind person -who- "sees" the snow.
        [snip]
  Mute.
  From Franklin's, "interrupt" means to:
        intrude so as to hinder OR end continuity
  Reduction of flow, hinders outflow.  Therefore, any impeding
the flow of water is "interruption" of it.  This is not consistent
with the one defintion you are using above.
        [snip]
  Change may be either interruption or not.
  Yes, the metabolism of bilirubin does.
  Ah, you just gave me "any function", is it "all functions" or
"any function?"
        [snip]
  Let us look at the respiratory drive.  If we were to look at
the output in terms of breath or not breath then it is digital,
however, if we were at the output in terms of respiratory rate,
it would be analog.  If we were to look at the brain stem neuron
responsible for stimulating the vagus nerve (which has a membrane
potential of around -90 millivolts), it operates in terms of
digital (fires or not).  If one were to look at the "group" of
neurons,  then I surmize its analog.
  Please define -what- you are looking at.
  Yep, for the most part, for example in the respiratory tract
whose columnar epithelial cells cilia operate on a very similar
idea.  Even, the flagella of sperm do.
        [snip]
  It depends upon what function you talking about.  For the
sake of discussion, the liver "does" the detoxification for
the body.
  When a human is in a coma, the individual never comes
in contact with those substances (which is the function
of the liver to take care of) resulting in no detoxification.
  Nope, I view your responses as ones bent on keeping what you
-assume- to be correct as correct.  Such a position is not
one open to discovery.
Take care,
John
