Old age and treachery will always overcome youth and skill.
You know you've reached middle age when a doctor,
not a policeman, tells you to slow down.
There was no respect for youth when I was young,
and now that I am old, there is no respect for age
- I missed it coming and going.
Forty is the old age of youth; fifty the youth of old age.
At 20 years of age the will reigns; at 30 the wit; at 40 the judgment.
You can't help getting older, but you don't have to get old.
Grow old with me! The best is yet to be.
