Using our technique, profound wrinkling was demonstrated to be independently associated with both habitual cigarette smoking and increased outdoor exposure in 1,104 white men and women. The variables of age and weight loss were recognized and controlled. For each ten-year age span between ages 30 and 70, among both men and women, the more exposed nonsmokers were less apt to be
