Old age is fifteen years older than I am.

There is always some specific moment when we become aware that our youth is gone but years after we know it was much later.

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

Nobody grows old merely by living a number of years. We grow old by deserting our ideals. Years may wrinkle the skin but to give up enthusiasm wrinkles the soul.
