When I was a child, my father would smoke around my family like nobody's business. Smoking, in fact was legal in most public places when I was a youth. I frequently got sick from 2nd hand smoke. Even now, at age 45, I have severe breathing issues due to allergies & bronchitis I developed during childhood because of 2nd hand smoke. My image is just one of the many smoke particles that plague victims of 2nd hand smoke.
