>Most of the research has come from studies of nonsmokers who are married to a smoker. Those conclusions are also backed up by further studies of workplace exposure to smoke

I suggest you don't marry a smoker, or work in a bar where they allow smoking. Otherwise, you'll be fine. You'll probably be fine either way. The increased risk is minimal (1-4%?) and requires years and years of constant exposure.
