Most of these things are entirely inaccurate
Stating that a cigar takes away '11 minutes of your life' is preposterous considering you haven't taken into account whats in the cigar, and how much of the cigar is actually inhaled (considering you do not inhale a cigar)
Saying one cigarette takes of a certain amount of life is wrong too. For example, If i were to smoke a menthol cigarette i would begin to crystallize my lungs obviously decreasing my lung capacity, while if i smoked a non menthol full flavor my lungs would slowly dissipate.
Think of lights compared to regulars. A light uses one less sheet of paper and has air holes that burning tobacco escapes from, though its just as long as a normal cigarette. A lot of the tobacco from a light cigarette is burnt in to the air, and therefore, is not hurting you like a regular cigarette. A time can not be put on each cigarette.
I choose marlboro smooths...
