Marlboro Light 100s are my dad's choice of cigarettes, but I don't believe he has ever smoked as many as three packs a day . . . maybe less than a pack a day when his smoking was at its heaviest. Up until now, he had been tapering off a little bit, mainly because the price of cigarettes has gone up so much, and he can't justify the expense. But otherwise, he's been smoking since he was thirteen, so . . . I'm amazed he's lived this long in spite of his smoking; I believe a doctor even warned him a decade ago he may only have five more years at most if he didn't give them up.
Nevertheless, I think all of these diagnoses associated with his smoking (and this after he had unrelated cancer last year due to a tumor in his neck), has finally scared him straight.
