pollutants

Pollution is often believed to be a factor in premature aging. Air pollution, as a cause of chronic pulmonary disease, might speed up the decline of ventilatory performances usually associated with aging. The risk of air pollution is not limited to industrialized areas. For example, to keep warm during cold nights, the natives from the highlands of New Guinea bum fires in small closed huts. They inhale extremely high levels of smoke. As a result, in this study pulmonary disease appears at an early age and is present in 78 percent of the subjects over 40.
