So I accept they're bad for me and my neighbors--how bad, roughly? I like wood fires, and intend to keep lighting them with about the same frequency as now (every 6-18 months or so), but is this going to take a year off my/my neighbors' life expectancy? Just like driving has a pretty high chance of death, I suspect it's "worth it" when the utilities come out. (Edit: Or as fmkamchatka mentioned in a better example, eating fast food every now and again.)
