1. A method of selectively eliminating senescent cells to relieve symptoms of a pulmonary disease or disorder that is not a cancer in a subject, the method comprising: administering in or around a lung of a subject in need thereof a therapeutically effective course of therapy of a pharmaceutical composition that contains an aryl sulfonamide that selectively inhibits Bcl-xL;wherein the pharmaceutical composition is formulated such that the aryl sulfonamide contacts senescent cells located in or around the lung that are causing symptoms of the pulmonary disease or disorder,wherein the senescent cells are defined as non-cancerous cells that express p16,wherein the therapeutically effective course of therapy includes:(1) a treatment phase during which one or more doses of the pharmaceutical composition are administered to the subject so as to contact and selectively eliminate the senescent cells from the lung, followed by(2) a therapeutic phase lasting at least two months, during which the pharmaceutical composition is not administered, and the symptoms of the pulmonary disease or disorder are relieved in the subject as a result of the selective elimination of the senescent cells by the administration of the one or more doses of the pharmaceutical composition during the treatment phase. 2. The method of claim 1, wherein the aryl sulfonamide comprises the structure shown in Formula (II), or a pharmaceutically acceptable salt thereof: wherein X3 is Cl or F; X4 is azepan-1-yl, morpholin-4-yl, 1,4-oxazepan-4-yl, pyrrolidin-1-yl, N(CH3)2, N(CH3)(CH(CH3)2), 7-azabicyclo[2.2.1]heptan-1-yl or 2-oxa-5-azabicyclo[2.2.1]hept-5-yl, and R0 is wherein X5 is CH2, C(CH3)2, or CH2CH2; X6 and X7 are both hydrogen or are both methyl; and X8 is F, Cl, Br or I; or X4 is azepan-1-yl, morpholin-4-yl, pyrrolidin-1-yl, N(CH3)(CH(CH3)2) or 7-azabicyclo[2.2.1]heptan-1-yl, and R0 is  orX4 is N(CH3)2 or morpholin-4-yl, and R0 is 3. The method of claim 1, wherein the aryl sulfonamide is ABT-737 or a pharmaceutically acceptable salt thereof. 4. The method of claim 1, wherein the aryl sulfonamide is ABT-263 (Navitoclax) or a pharmaceutically acceptable salt thereof. 5. The method of claim 1, wherein the aryl sulfonamide also inhibits Bcl-2. 6. The method of claim 1, wherein the lung disease is chronic obstructive pulmonary disease. 7. The method of claim 1, wherein the lung disease is lung damage caused by cigarette smoke. 8. The method of claim 1, wherein the aryl sulfonamide is administered as an aerosol.
