Smokers Minus Ten

Findings from a half century of research on the dangers of smoking show cigarette smokers die on average 10 years earlier than non-smokers. Fortunately, kicking the habit, even at 50 years of age, can halve the risk. This study is quite remarkable as studies lasting 50 years are highly unusual. More remarkable is the researcher who initiated the research 50 years ago, Oxford University Professor Richard Doll, was still involved in the study.
