It is clear that septum deviation cannot be a primary cause of mental illness. It is also clear that 80% of population do not have a deviation to the same extent; and within the percentage of the ones with strong deviation, only a percentage had lives that brought them to depression and near problems. You should see that we are not talking about the 80% of population, but of a much smaller slice.
Furthermore you might consider that in some cases (I feel in most cases) metal problems can be the result of concomitant eventuality, and healing may pass through a selective and incremental resolution of problems in order to establish a stable enough well-being.
I find interesting what you are saying about oxygen saturation of blood. I am going to search this, unless you have a link on your bookmarks .
However, not only the oxygen intake interests me; muscular/organ reaction interests me too, which may be of some importance.

As a joke you have a septum deviation and you have 18152 posts on psychcentral.. joking
