Story at-a-glance
Inside your nasal passages are two areas containing nearly 6 million olfactory receptor cells that allow you to detect and differentiate thousands of different scents
Your olfactory nerve enters near the base of your brain where scent is first processed, in an area with memory and emotions; this may be why scent can awaken strong memories and why your loss of smell may predict the onset of neurological problems in the following five years
Animal studies demonstrate an aversion to others who are sick based on odor, which may help protect group health; the ability to detect specific scents from people with disease is being tested using dogs
The inability to detect smell has been associated with a four times greater risk of death in the following five years; loss of sense of smell may be related to a zinc deficiency
