I'm Marvelous Marvin Hagler. Do you know what I think is the most dangerous part of boxing? The smoke-filled arenas. I work out, exercise, and eat well. When on fight night, I'm breathing the poisonous smoke of thousands of cigars and cigarettes. For your health and mine, knock cigarettes out of your life. Contact your American Lung Association. Healthy lungs are a matter of life and breath. For more information visit www.aclu.org
