" If you ever live to be as old as I am you will find many things strange.” “You never seem old.” “It is the body that is old. Sometimes I am afraid I will break off a finger as one breaks a stick of chalk. And the spirit is no older and not much wiser.” “You are wise.” “No, that is the great fallacy; the wisdom of old men. They do not grow wise. They grow careful.” “Perhaps that is wisdom.” “It is a very unattractive wisdom. "
