Until rereading the above I had not realised that my opinion ,that there is an interchange between the emotional/psychological and the physical , originated in something I read/wrote so long ago !. As below;-

(Allen PI0I Chronic Miasms) "On the other hand, when the growth was removed by surgical measures it often became recurrent, or some new development succeeded it, frequently of a nervous or mental nature, that was difficult to remove, if not incurable."

As I have siad it is my opinion that this exchange takes place via the pituitary , which 'bleeds' excess pressure in one area over to the other.
