A very thought-provoking post; I confess I had seen mental traits as learned rather than hereditary, but I see that perhaps there are more elements to it than that.
It is so easy to forget that body and mind are connected, what with all of the white noise that everyday life can become.
I find your posts refreshing; and while I am just a faceless lurker on the interwebs, I really appreciate your sharing of thoughts. They are extraordinarily refreshing. So thankyou. ^^
