Famous quotes containing the word age:
“Old age is a tyrant that forbids us upon pain of death all the pleasures of youth.”
—François, Duc De La Rochefoucauld (16131680)
“When you get to my age life seems little more than one long march to and from the lavatory.”
—John Mortimer (b. 1923)
“It is not however, adulthood itself, but parenthood that forms the glass shroud of memory. For there is an interesting quirk in the memory of women. At 30, women see their adolescence quite clearly. At 30 a womans adolescence remains a facet fitting into her current self.... At 40, however, memories of adolescence are blurred. Women of this age look much more to their earlier childhood for memories of themselves and of their mothers. This links up to her typical parenting phase.”
—Terri Apter (20th century)
