The lifespan of a smoker tends to be ten years shorter than that of a never-smoker. But smokers who quit by their 40th birthday can expect to live nearly as long as those who never took up the habit, according to a new analysis of health survey and death record data from the US.

“Quitting smoking before age 40, and preferably well before 40, gives back almost all of the decade of lost life from continued smoking.”
