Answers.comÂ® is making the world better one answer at a time. Smells usually travel through the wind. If you're outside playing volleyball, you'll probably get the scent of mom's fresh baked blueberry pie sitting on the windosill waiting to be cooled and then eaten. Making you hungry? Well all smells can't travel without a boost, that's why you have a nose that picks up the scent of perfume a mile away.
Smells can also signal danger, fear, or dread. Although our sense of smell is our most primal, it is also very complex. To identify the smell of a rose, the brain analyzes over 300 odor molecules. The average person can discriminate between 4,000 to 10,000 different odor molecules. Much is unknown about exactly how we detect and discriminate between various odors.
