For this discussion, you will conduct a "mini experiment". Give several people a variety of scents to smell (5-10) and ask them for specific memories that they had when smelling each. Don't just take "it smells good or bad" for an answer, ask for memories. Use 5-10 different scents from a wide variety of smells like vanilla, cinnamon, something medicinal, grassy or woodsy scents, salty, fishy, etc. Then record each memory they recalled with each scent.
