Good smelling things
I’ve never been much of an olfactory dependent person, I think most people aren’t. On the other hand I do know that my sense of smell tends to be better then most other peoples.
Some recent good smells I’ve noticed:
Barbeque
Tomato Plants
The air when rain is coming (called “petrichor”)
Fresh cut Pine trees (vastly different then the typical Christmas Tree smell)
Garlic
Sautéed Onions
Good quality dirt
I’m sure a physiologist (and even a phycologist) might have something to say about the fact that all the smells are food related, or outdoorsy.
