I agree that the people robustly rejecting the idea of any dangers to log burners, are the ones who have spent several thousand £££ and now have to justify it to themselves.
I don't need to justify anything, thanks. The cost of gas speaks for itself.
I'm rather dubious of the many claims about what will kill us next. One week it's log burners, the next it's red meat (good news though, this week red wine is good for you, get it before they change their minds again). Often the headline will say that X increases the risk of Y by a gazillion percent, but fails to give any context, such as how big the base is.
How many people per year die prematurely because their parents had a log burner in their house? How does that compare to the 1,600 killed on the roads, or the 700 murders each year?
From anecdote I notice that I breathe in more shit when I'm on my bike and stopped behind an older car, though of course I'm probably more at risk from the possible actions of the driver. I'm very glad that I spend as little time as possible in cities, that's where the real air pollution is.
