In the last year or so I have become very sensitive to scents and smells. Makes be very short of breath. Even those that are lingering but the source is no longer there such as in a elevator when the person wearing the perfume has left. And how do you all handle it. Recently had to ask a neighbor not to wear so much perfume when visiting and found it embarrassing for both of us. I'm also trying to clean without chemicals. Interested in your thoughts and ideas.
