Smokers 'will die 10 years early'

Smoking cigarettes cuts an average of 10 years off a person's life, a landmark study suggests.

But it also shows that quitting at any age reduces the risks of dying from smoking-related diseases.

The findings, published in the British Medical Journal, are the culmination of a 50-year study involving 34,439 men.

The study, which began in 1951, was the first to confirm the link between smoking and lung cancer exactly 50 years ago.
