I don't know. I have such an extrem nasal septum curvature my cavernosa and smellbuds (Don't know if any of those are correct translations) are totaly dysfunctional. I sat once when I was younger in the livingroom after school an was playing there for more than an hour and as my mother returned from the doctor with my brother who was sick she almost blacked out from the smell in there. my brother vomited right before they left and my mother had no time to clean it. I have smelled nothing. There are only few things strong enough for me to smell them. paprika for some reason. And I hate it.
