Yes. Smelling is a very important sense. It triggers the most memories, you can recall things better if there is a smell involved rather than relying on sight, taste, etc. I still remember that Aaron smelled like gain laundry detergent, coffee, and cinnamon gum the first time we met. With that memory, I can easily recall the time, day, what I was doing, what I was wearing. To be more on topic though, we do somewhat choose our mates based on that sense, it is a qualifying factor, a strong one.
