You are all wasting your time trying to talk sense into smokers,they dont believe the doctors or the more sensible humans on this planet.They always know someone who is 120 year old and smoked from the age of six and never people who have never smoked and suffer the misery of illness caused by passive smoking.The only time they realise is when they are on their deathbed when giving up is too late.To all sensible people it is obviously the best thing that has ever happened,long live us all.
