Somehow, some way, who knows? About 5 years ago I was towards the end of menopause. It was the Friday after Thanksgiving. I was removing the meat from a 20+ lb turkey and stewing the carcass. It smelled just horrible. I kept on going. Just as I was about to trash the entire bird, thinking that somehow I'd managed to poison it (which I've never done in my life), my husband came down and said, wow, if there is anything better than a roasting turkey on Thanksgiving, it is the aroma of turkey soup the day after.
I realized that somehow, my sense of smell went off. Really off. I've heard of people losing their sense of smell, but things started smelling truly bad, things that I normally loved.
It gradually came back. With one exception. Why can it not be something Fattening or bad for me? Cucumbers and watermelon. They smell exactly the same. I rationally realize that they have a mild flavor and aroma, but they still smell and taste repulsive. And I used to love these, really love them! Dear force in heaven, give me back cucumbers and watermelon! Please, I want them back!
