Your Sense of Smell/Taste

Recently in my Psychology class, we learned about how certain smells can make you cognitively remember past experiences. For example, the smell of freshly cut grass could take you back to when you were 6 years old playing around in the grass at a park. Also, certain tastes can highly affect your eating habits. You could eat a certain food dish and coincidentally get sick right after and never want to eat that food item again. When this happens your mind ties together you getting sick with the food you had recently eaten to morph it into one situation therefore imprinting in your mine the side-affects of the certain food.
