Difficulty smelling

Difficulty smelling

I recently saw a Korean movie.  A man tried hard to smell anything, but in vain. He kept sniffing, hoping to smell anything.  Smell disorder can arise from many causes.  He seemed to smell something long after he became unemployed.  His smell disorder might come from work stress.
