Can smell convey emotions?

Bonnie Blodgett never stopped to appreciate her sense of smell – until she lost it.

Suddenly, the St. Paul, Minn., gardening expert and writer could no longer enjoy the loamy scent of soil, the mouth-watering aroma of freshly baked cookies, and the invigorating fragrance of a walk in the woods. Nor could she detect unpleasant odours, like spoiled milk or a pan left burning on the stove.
