Fun fact. Have you heard about the nasal cycle, an alternation of the amount and speed of airflow through either side the nose with a period of about 2.5 hours?
I had noticed it in myself forever ago but had never heard anyone talk about it until some day in the last 10 years I searched for it and found that it was a well-known phenomenon.
The scent sensitivity range benefit is something I only learned today as I read the Wikipedia article.
