Now that we can use the internet to access almost anything you’d want to see and/or hear, we should make museums that archive different smells. You could find new smells you might have not experienced otherwise, or find some nostalgic smell to bring you back to a moment in your past.
Interesting idea, but I think olfactory fatigue (aka going “nose blind”) would get you fairly quick.
Is there a way to reset your nose after olfactory fatigue? Sorta like a palate cleanser for your nose?
