There's an old man in our village calling Old Joe who said to be 110 years old. This
can't be proved though he doesn't have a birth certificate. All his personal papers were
destroy during the World War Ⅱ. I don't know if he really is so old, and it doesn't
matter. He certainly looks very old. Of course, he is often asked question by people who
want to be told the secret of long life. Old Joe always answered them like this, "If you
are offered a cigarette, never accept it; if you are annoyed by someone, never lose his
temper; and if you are asked foolishly questions, never answer them."
