According to the Webster dictionary the word Pheromone refers to a "chemical substance secreted and released by an animal for detection and response by another." Popular press you may recall have often referred to these hormones as the basis of instinctive reactions such as sexual desire and other mood and emotional aspects including fear. I was wondering if readers have anything to say about how potentially it could be our reaction to pheromones secreted by others and ourselves that could be "part" of the causation of mental and emotional disturbances. Has there been any research as to the effect of sensing (smelling) these some what influential chemicals that we secrete on a daily basis? Could it be that our emotional and mental states are dependent on the subliminal smelling of these hormonal chemicals?
