Smells tasty...or does it?

Last night, a friend staying with me made us a pot of coffee. I had just placed some salmon in the oven to bake. I still had the smell of the fish in my nose when I took a sip of my coffee.
I nearly spit the fishy-tasting coffee mouthful out all over the table.
It got me thinking...
If it's true that 80% of taste is smell, what does my milk taste like when my son is nursing and the smell of baking salmon is in the air? Or better yet chocolate chip cookies baking? Or does the milk taste like how I smell? (I often smell like old milk)
It'll make me think (or smell) twice the next time he spits up his milk...
