“SMOKING kills”, declares the message on my packet of cigarettes.

Yet it has not killed me.

I became addicted to smoking fags on being conscripted into the army in May 1941, a week before my 20th birthday, when the habit was ‘de rigueur’.

I have since puffed my way through about 500,000 cigarettes, much to my financial disadvantage, admittedly, but with no health problems – apart from a smoker’s cough and some congestion of the chest.

I still smoke more than 20 daily.

I have not the least wish to advocate an addiction, but can the medical profession explain why I have survived into old age, whereas so many other unfortunate smokers have not?
