The article summarises how smoking accelerates the decline of your lung functions.
"Smoking is injurious to health" - how many times have we come across this slogan in different forms of media.Yet the smokers among us seem to be undeterred by it.
The above graph is called the Fletcher Peto curve and shows the effect of smoking on lung function (FEV1 - forced expiratory volume in 1 second).
The first(topmost) curve demonstrates the normal age related decline in lung function in a person who has never smoked is not susceptible to smoke.
On the other hand the dark black line demonstrate the accelerated decline in lung function of a patient who smokes regularly and is susceptible to smoke.Notice the rapid decline in the lung function of the person on his way to early death.
In between are the lung functions of patients who have quit smoking at various ages( viz. 45 and 65 yrs.). One can clearly see in the graph that the early a patient quits smoking, the more is the years of life gained by him but sadly his lung functions will always be below the normal levels (i.e. if he had not smoked).
So friends, the decision is yours. Do not take up smoking any time in life if you are a non smoker and if you are in the other group, STOP SMOKING NOW!
