Did you know the inability to distinguish smells can be a sign of mental illness?
Sadly, many individuals that suffer from mental illness lose their ability to distinguish smells as their disease worsens. There is also research showing that deficits in one's sense of smell can act as a base in assessing certain types of mental disorders such as depression as each mental disorder has its own distinct pattern of deficits in someone's ability to smell.
Moral of the story, don't take your sense of smell for granted! It's a sign of mental and physical health.
