POLLEN

Thankfully, I don't suffer from allergies. But many people do, and this time of the year is a difficult one, with all of that pollen blowing around. A number of my students are affected, and they didn't look very good today.

I am not surprised. Birch pollen is a big irritant, and a level of 100 is considered high. Yesterday it was measured at 4,696, which is the highest ever recorded in Denmark.
