Even when I started smoking at 18 I knew it was bad for me. It took me quite a while to take any notice of this fact but thanks to the smoking ban I haven’t touched a cigarette in four years and my antipathy is now such I even cross the street to avoid smokers. This was quite difficult on a recent trip to Austria where people still smoke all over the place. Why is that? Is it because Austrians don’t think smoking will make them ill? Or is it because they value personal choice over state intervention, even when that creates risks for public health? Or is it simply because they don’t think banning things works?
