Scent, emotion and memory

Was talking to my mom this morning about how scent is closely tied to memory and more specifically, emotion and memory. Found this really interesting article about how it works. I know for me, the smell of suntan lotion makes me think of my days on the beach here. Certain colognes are ruined for me forever by old boyfriends. And like Will Smith says, the smell of a grill really DOES spark up nostalgia.
