Rarely do I get a common cold now, with little coughing (if any).
My body is able and willing to fight it off quickly.
In smoking days, Colds were Bronchitis, big Meds including Cortizone and wretched weeks.
I found this article on the website of Dr. Michael Klaper, who is an advocate of Prevention and Nutrition based medicine.
He is a consultant for NASA.
"SMOKERS, PLEASE NOTE:
The most common and serious cause of bronchitis is cigarette smoking.
Smokers keep a continuous thermal and chemical burn percolating in their lung linings. As a response to the smoke assault, the bronchial tube linings secrete a sugar-rich mucus, which accumulates overnight and pools in the bronchial tubes.
The microbes flourish and then digest the mucus, altering its color and, in the morning, the bronchitic person typically sits up coughs out this colored phlegm – the classic “smoker’s cough.”
Chronic bronchitis in smokers never completely clears from the lungs as long as the person continues to smoke.
Over the years, the constant inflammation and infection fosters scarring
and permanent narrowing of the bronchial tubes. Breathing out through narrowed bronchial tubes creates a back-pressure
which, in turn, blows out the lungs’ microscopic air sacs (alveoli) where oxygen enters the blood.
This results in emphysema, a dreadful disease that steals your breath and eventually, your life. Of course, the smoke of any burning leaves is also filled with carcinogens and, thus, cigarette smoke spawns the lung cancers to which so many smokers fall victim."

this line,
"Smokers keep a continuous thermal and chemical burn percolating in their lung linings."
gives me the shivers...
