Okay, not really scientists. Just me.
The pollen in the air is playing havoc with whatever portions of the body are responsible for me breathing air as opposed to viscous fluids. I may need gills.
I discovered a side benefit. I drink green or white tea every morning, sometimes flavored. This morning it was goji berry and pomegranate flavored. If you drink these teas while your sinuses are stuffy, there's a pleasant little side effect. At any point later in the day, when you sneeze or blow your nose, you get a little olfactory hint of fruit.
It's like the bouquet of a fine wine, and it lasts all day.
