The doctors broke it down this way: Those who had never smoked had an extra 18 years of their life past 70 years. Participants who had given up smoking before 70 could expect to live another 16 years. Finally, those who continued to smoke could live another 14 years past their 70th birthday, losing four years on those who never picked up the habit.
