Everything's relative, sure, but pay close attention to your sense of well being the next time you're in a car with an air freshener, or someone sprays febreeze

Everything's relative, sure, but pay close attention to your sense of well being the next time you're in a car with an air freshener, or someone sprays febreeze in a room. You'll probably start to feel uneasy and/or have dulled senses very quickly. Do that often enough, and the abuse adds up.
