   Which I suppose excludes them as RF transmission ranges, unless light is   
   allowable.  Would frequencies significantly higher than those be usable?   
     I've forgotten what I learned in college "freshman physics", mainly   
   because the course was horrible.  It was one factor in my decision to   
   leave that university, even though I wasn't a physics major.

   But in this case they're not placebos.  Simply being accepted there   
   won't do a thing toward curing stuttering or other speech impediments.   
   Even there, it's still necessary to work at classes and exercises or   
   whatever they do.

   For an excellent and honest perspective on the medical world as it was   
   at the time (1970?), read the book "A Surgeon's World" by William F.   
   Nolen, a practicing general surgeon.  One G.P. in his town is a lousy   
   doctor with a great bedside manner, and loved by his patients.  However,   
   Nolen brought his own family to a G.P. who was brusque, almost   
   unpleasant, but did a very good job diagnosing and curing whatever was   
   wrong.  Guess which of the two made more money.

   Although I think most people are unaware that low sodium level is a problem.   
      
   I see that this thread has also gone OT, although the brief discussion   
   of security seems to be over.
