heheheh...same here...routine 'listen to the lungs' events and the Doc will comment that i have better sounding lungs that people half my age or some such...
then i inform them ive smoked for 30+ yrs and can still blow a candle out from across the room...they say i better quit while im ahead, and i agree, but its definately not settled science, or guaranteed to cause a problem...
LOL! Nobody likes a quitter. (I almost said quilter)
