Crucially from my perspective it gives an accurate picture of the health risks of smoking and of the prospects of my own mortality. To summarise:
At any age you are more likely to die if you are a male than a woman.
Roughly speaking if you smoke you add about 5-10 years to your life. Thus a 60 year old smoker has about the same life expectancy as a 65 year old non-smoker.
Compared to a non-smoker a 60 year old male smoker has about double the risk of dying from vascular (heart or stroke) disease and about 25 times the risk of lung cancer. Ex smokers have experience somewhere between these extremes but still a greatly increased risk of lung cancer.
Overall of 1000 60 year old male individuals, 115 never-smokers will die within 10 years, 256 smokers will die and 166 former smokers will die.
Of 1000 60-year old women only 84 never-smokers will die within 10 years, 167 smokers will die and 125 former smokers will die. Women smokers from age 40 on have a much higher risk of dying within 10 years from lung cancer than from cancer of the breast. At age 65 the difference is a factor of 8.
This is only a sketch of the main conclusions. Well worth a more careful view.
