In Japan, when it gets warm an enormous number of pollen of cedar wander in the air. It is still February, but I feel symptom of pollenosis. After that, I started to think about pollenosis.

Pollenosis is a kind of allergy. Old Japanese planted many many cedar a long time ago, so pollenosis almost means allergy of cedar’s pollen in Japan. Now that it is called national affliction of Japan. It is merely pollen, but many people are suffering from it.

I think all human being is weak to endure the changing environment after thinking about pollen. There is only slight change for us in growing up the numbers of pollen, however human beings react hypersensitivity. It may be that our gene do not have arrangement of changing environment.
