I have really no sense of smell. I haven't been able to smell much of anything for probably about a decade or so.
It is really kind of sad because there are some things that I honestly don't know what they smell like because I can't recall ever smelling them.
As for the bad things I can't smell those either.
One thing that I can say I DO smell though are salted foods - like popcorn and french fries. I am not really sure why but I have always been able to smell those - especially popcorn.
My sense of taste is VERY sensitive as well so I am not sure how much of that sense of smell and sense of taste being tied together is true. People have always asked me that but I love food and can taste even the slightest seasonings sometimes.
Have a good one,
Lindsey
