The secret to a happy life is revealed by Bill (88) from Carlton, Victoria: "Try to have a laugh everyday. If you feel miserable, watch something funny on television, or get a joke book and read from that each day. When you are laughing it is hard to dwell on your own crap. That might mean reading a lot of joke books and watching a lot of funny television on some days, but eventually your mind will know how to think happy and you will become a happier person too. So get laughing, that's what I say!"
