Famous quotes containing the words life and/or span:
“We shall make mistakes, but they must never be mistakes which result from faintness of heart or abandonment of moral principles. I remember that my old school master Dr. Peabody said in days that seemed to us then to be secure and untroubled, he said things in life will not always run smoothly, sometimes we will be rising toward the heights and all will seem to reverse itself and start downward. The great thing to remember is that the trend of civilization itself is forever upward.”
—Franklin D. Roosevelt (1882–1945)
“... we’ve allowed a youth-centered culture to leave us so estranged from our future selves that, when asked about the years beyond fifty, sixty, or seventy—all part of the average human life span providing we can escape hunger, violence, and other epidemics—many people can see only a blank screen, or one on which they project fear of disease and democracy.”
—Gloria Steinem (b. 1934)
