Youth is a silly, vapid state, Old age with fears and ills is rife; This simple boon I beg of Fate - A thousand years of Middle Life.

In youth, the days are short and the years are long. In old age, the years are short and days long.

That's the trouble with you young people. You think because you ain't been here long, you know everything. In my life I already forgot more than you ever know.

When you're young, the question is "What can you do for me?" and when you're old the question is "What can I do for you?"

As we grow old the vigour of youth is exchanged for life experience and wisdom.

Forty is the old age of youth; fifty the youth of old age.
