According to what he told Livy in one of his courtship letters
(shortly before quitting for a time after his wedding, I think; I
don't have my copy of that volume of the published letters handy), he
smoked 300 cigars a month; that would figure at around ten a day, not
really above average for the typical male cigar smoker in the
nineteenth century before the popularity of cigarettes. Remember,
Grant died of throat cancer.
