On Age

              

(from Reaperman by Terry Pratchett)

YOU ARE OLD AS YOU THINK YOU ARE.

"Huh! Yeah? Really? That's the kind of stupid thing people always say. They always say, My word, you're looking well. They say, There's life in the old dog yet. Many a good tune played on an old fiddle. That kind of stuff. It's all stupid. As if being old was some sort of thing you should be glad about! As if being philosophical about it will earn you marks! My head knows how to think young, but my knees aren't that good at it. Or my back. Or my teeth. Try telling my knees they're as old as they think they are and see what good it does you. Or them.
