Sorry Ken. My response was to something that DynaSoar wrote earlier that I
wanted clarification on.
Also I didn't know that you were the one that made the comment about
electric and magnetic fields. I read the post and didn't look at who posted
it. All that was salient about it was that the statement was wrong. With
respect to the nervous system then your right then, I thought you meant in
general physics. (Actually in perspective, my comment was entirely
irrelevent especially seeing how it was discussed so long before).
