Aware of allergies. Just don't come near me wearing any type of fragrance! I have to leave the room. And don't sweep the floor. The worst "illness" I've ever had was a result of old dust. We all need to be aware of the many "allergies" and "sensitivities" most people have these days. Including those who do not even realize why they feel unwell. Fortunately, I am not allergic to dogs; life is "hardly worth living without one."
