“Youth lasts much longer than young people think.”

“...beds last on an average much longer than marriages...”

“Have you come over time to think that you know more now than you did when you were young, know less now than when young, know now there is so much more to know than you knew there was to know when young that it is moot whether you think you knew more then than now or less, or do you now know that you never knew anything at all and never will and only the bluster of youth persuaded you that you did or would?”

“‎"Does all the beauty of the world stop when you die?""No," said the Old Oak; "it will last much longer - longer than I can even think of.""Well, then," said the little May-fly, "we have the same time to live; only we reckon differently.”

“Old men tend to forget what thought was like in their youth; they forget the quickness of the mental jump, the daring of the youthful intuition, the agility of the fresh insight. They become accustomed to the more plodding varieties of reason, and because this is more than made up by the accumulation of experience, old men think themselves wiser than the young.”

“Genius lasts longer than beauty”
