For Sweden #7 and Australia #9 they cite low smoking rates to explain longevity. Interestingly, they don't mention smoking for the higher longevity countries, e.g. #1 Andorra (44 % of men smoke, 40% of youth 18-24), or #6 Japan (59% of men smoke). At individual level, the oldest man and the oldest woman on record were smokers.
Madamme Jeanne Calment lived 122 years 164 days (she smoked since her teens).
Shigechiyo Izumi 120 years and 237 days. They were the only two humans who lived beyond 120 years of age.
The oldest human who completed a full marathon (at age 101) smoked since his teens and had few cigarettes through the race as well.

These are not one-off kind of oddities, since in animal experiments, smoking animals (even at 5 pack/day equivalent exposure) live longer (by ~20%) than non-smoking animals. They also remain thinner, healthier and sharper throughout. Tobacco is an ancient medicinal plant and like all medicinal substances, its use will statistically correlate with various health problems (e.g. people who use statins or blood pressure medications will have more heart attacks later than people who don't use them).
(see discussion & refs in this thread). In short, smoking is good for you (discussed also in thread1, thread2, thread3).
