    My grandfather Jack is 96 years old，and he has had an interesting life. He has travelled a lot in his life in the Far East. He visited the Taj Mahal in India and the Pyramids in Egypt. He hunted（狩猎） lions in Africa, and rode a camel in the Sahara Desert. He says the most beautiful place he has travelled to is Kathmandu in Nepal.

    Jack has married twice. His first wife died when she was 32. He met his second wife Maria while he was cycling round France. They have been married for 50 years, and they have lived happily in a small village since they got married.

    Jack says that he has never been ill in his life. The secret of good health, according to my grandfather, is exercise. He goes swimming every morning. He has done this since he was a boy. He also has a glass of wine every night！Perhaps that is his secret！
