This post reminds me of a class I had during my undergraduate studies. It was a medical microbiology class. The lecturer was saying that "smokers are liable to die young", my voice came underground to add very before young. The slogan now became Smokers are liable to die very young. The lecturer adopted it as well as my contemporaries.
@lawkay, Your neighbour (smoker) might live a bit longer but not as long as he should live if he didn't smoke.
That's the point!

It's a great post. Keep it up
