One can advise comfortably from a safe port. [ Schiller ]

The feeling of friendship is like that of being comfortably filled with roast beef; love, like being enlivened with champagne. [ Johnson ]

One couldn't carry on life comfortably without a little blindness to the fact that everything has been said better than we can put it ourselves. [ George Eliot ]

In the matter of diet - which is another main thing - I have been persistently strict in sticking to the things which didn't agree with me until one or the other of us got the best of it. Until lately I got the best of it myself. But last spring I stopped frolicking with mince-pie after midnight; up to then I had always believed it wasn't loaded. For thirty years I have taken coffee and bread at eight in the morning, and no bite nor sup until seven-thirty in the evening. Eleven hours. That is all right for me, and is wholesome, because I have never had a headache in my life, but headachy people would not reach seventy comfortably by that road, and they would be foolish to try it. And I wish to urge upon you this - which I think is wisdom - that if you find you can't make seventy by any but an uncomfortable road, don't you go. When they take off the Pullman and retire you to the rancid smoker, put on your things, count your checks, and get out at the first way station where there's a cemetery. [ Mark Twain, Seventieth Birthday speech ]
