I have severe allergies, and I live in a place that is highly polluted. It was not until I started traveling for work and vacations in the Southwest that I realized my allergies were better—less headaches, sinus infections, and fewer aches and pains from medications.
I realized I breathed better and had less problems with allergies in less polluted areas. My mother had COPD, and I do not want to end up like she did, not being able to breathe or socialize outside because of air pollution.
Life is just no fun or as she put it, worth living when you cannot breathe. It causes all kinds of other aches pains and health related problems in your body.
