Hi Mike,  

The problem is that I know zero about this electrically inclined medicine.  I 
have to get busy and start reading about it.  And even if I do the reading, I 
have doubts that I would understand much of it..... 
But I will try :)  Thanks.

Barbara




  Hi Barbara,

  I can understand your reaction, since so many people are not 
  "electrically inclined" and it all seems a bit mystical.
