We are all trying to stay safe from COVID. Here is another preventative measure: Rinse your nose with salt water. Inhaled viruses such as COVID may be ousted by enhancing the natural cleansing of the nasal tissues with a saline solution made up of 3 teaspoons of kosher salt  1 teaspoon of baking soda added to a cup of warm water. Pour this solution into your cupped palm and inhale through one nostril while holding the other closed. Now switch nostrils. Repeat once or twice per day.
