You probably don’t like looking at that picture above. And I hear ya. But that’s what some of the streets look like in Paris. It’s something that’s become such a problem that the mayor of Paris has decided to try to tackle the issue, and I share his concerns, although progress is evidentially slow-going. But what confounds me, as well as others, is why do so many people in Paris smoke? And why is the number of smokers increasing in France, when the US and other countries are seeing a decline?
