When I requested that some of the 'brighter lights' on this list check out 
colored light therapy, Nenah was the only one who did so.  And she did it right 
and over time so she came up with the verdict that it was a very good 'stand 
alone' therapy.  I think I recall that phrase correctly.  To my knowledge, she 
never talks unless she speaks from knowledge and experience.  So, Nenah, let 
your caravan move right on!!    imho    pj
