I have made it a rule never to smoke more than one cigar at a time. I have no other restriction as regards smoking. I do not know just when I began to smoke, I only know that it was in my father's lifetime, and that I was discreet. He passed from this life early in 1847, when I was a shade past eleven; ever since then I have smoked publicly. As an example to others, and - not that I care for moderation myself, it has always been my rule never to smoke when asleep, and never to refrain when awake. It is a good rule. I mean, for me; but some of you know quite well that it wouldn't answer for everybody that's trying to get to be seventy. [ Mark Twain, Seventieth Birthday speech ]
