I admit it: I'm cheating, because I posted this to Facebook, too. So sue me.
Posting this will get me labelled as one of those damn reformed smokers, but there are people I love who smoke and I hope they will read this, because I want to enjoy their company for many years to come.
Some are old enough that they probably don't care about the 15-year time frame, but they should look at the short term benefits.
And there are even longer term benefits than are mentioned here -- I quit 30 years ago, and look at how handsome I am! :-)
