Mark Twain

"I have made it a rule to go to bed when there wasn't anybody left to sit up with; and I have made it a rule to get up when I had to. In the matter of diet, I have been persistently strict in sticking to things which don't agree with me, until one or the other of us got the best of it. I have made it a rule never to smoke more than one cigar at a time. As for drinking, when the others drink I like to help. I have never taken any exercise, except sleeping and resting, and I never intend to take any. Exercise is loathsome."
