Dear BBella,

It is generally episodic and therefore very annoying, but most of the time the patients can speak normally. It is thought to be caused by a person having been under extreme stress at some point in their life. One is not born with it. Note that BBella has described extreme stress in her life, and so she fits the clinical picture. Counselling can revieve the situation, and my cousin (with inherited depression) was totally cured by counselling and medication for her depression. BBella, please note.-As for the RLN, development of a prolonged neck in evolution with the RLN looped around blood vessels, dragged the loop bigger and longer. It still works just as well, and in the discussions about God's designs, one must remember that useful design is not always artisically beautiful design, as perceived by the disconnected onlooker. Again, the inside-out, upside-down and backward human retina can see one photon! Why? The design allows for high blood flow and very high nutrition. I think Dawkins probably knows this, but won't ever discuss these designs rationally. It will damage his position.
