to grow old

Growing old is the only way to live long.
The mature age is the one in which you are still young, but with much more effort.
What torments me most about the follies of my youth is not that I have committed them... but that I cannot do them again.
Growing old is moving from passion to compassion.
Many people don't make it to eighty because they waste too much time trying to stay in their forties.
At twenty, desire reigns, at thirty, reason reigns, at forty, judgment.
What is not beautiful at twenty, strong at thirty, rich at forty, nor wise at fifty, will never be beautiful, nor strong, nor rich, nor wise...
When you're over sixty, few things seem absurd to you.
Young people think old people are silly; the old know that the young are.
Man's maturity is to rediscover the serenity that he enjoyed when he was a boy.
Nothing passes faster than the years.
When I was young I used to say:
"You'll see when you're fifty."
I'm fifty years old and I'm not seeing anything.
In the eyes of the young the flame burns, in the eyes of the old the light shines.

There is always a boy in every man.

Young people walk in groups, adults in pairs and old people walk alone.
Happy is he who was young in his youth, and happy is he who was wise in his old age.
We all want to reach old age and we all deny that we have.
