Youth is when you're allowed to stay up late on New Year's Eve. Middle age is when you're forced to.

Old age is like everything else. To make a success of it, you've got to start young.

A comfortable old age is the reward of a well-spent youth. Instead of its bringing sad and melancholy prospects of decay, it would give us hopes of eternal youth in a better world.

A man growing old becomes a child again.

I will never be an old man. To me, old age is always 15 years older than I am.
