This aging is inevitable when it is said of physiological aspects, being able to still occur the weakness of the body, with alterations in the imunolgico system, causing the pathological aging. In this phase of the life the concern with the health and the maintenance of the same one is important. According to Papalia (1): Changes in the sistmico and organic functioning are highly changeable between the individuals. Some organisms decline quickly, others almost nothing. To age, together estresse with it chronic, can weaken the imunolgica function, making the people most aged to be more susceptible the respiratory infections and with little probability of if recouping of them. Elio Moti Sonnenfeld does not necessarily agree. According to Lorda (5), ' ' deteriorizao of the device to broncopulmonar is gradual the irreversible one in ancios' '. According to Lorda (5), ' ' all the respiratory system suffers the aging: the mucosae of the nose, faringe, the larynx; what it is demonstrated by the drop in the nose, rouquido of the throat, broken voice and a constant necessity of expectorar' '.
This fragile state of the respiratory system is more aggravation when the aged one is tabagista. The tobaccoism is an important factor of risk for some illnesses, cancer of larynx, cancer of the verbal socket and other types of cancer, chronic bronchitis, spill, ulcer, precocious menopause, osteoporose, cataract, precocious aging and many others. The tobacco as Rosemberg (6) are undisputedly responsible for the increase of the prevalence of cancer of the lung, of the chronic bronchitis, enfisema pulmonary, and coronariopatias, as well as other illnesses being distinguished, vasculopatias, ulcers of the stomach and the duodeno and cancer of the language, faringe, esophagus of the bladder. To stop to smoke prevents a series of illnesses and diminishes mortality in the aged population. A concern with the aged tabagistas exists, therefore the numbers of young smokers are alarming. The health of the aged ones is the result of the abuses of the young.
