All the world's a stage and most of us are desperately unrehearsed.
Sean O'Casey (1880 - 1964)
You don't stop laughing because you grow old. You grow old because you stop laughing.
The truth is always a compound of two half- truths, and you never reach it, because there is always something more to say.
Tom Stoppard (1937 - )

And a bonus extra ... just 'cos I can :)
I am an old man, but in many senses a very young man. And this is what I want you to be, young, young all your life.
