Alice is a young woman. She likes to exercise for her health. She walks five kilometers before breakfast every morning, and goes swimming twice a week at the swimming pool. She doesn’t smoke and never drinks wine(酒). She doesn’t eat chocolate, and she doesn’t eat sweet and fatty foods.

One day Alice was on her daily walk when she saw a man sitting in a chair. He looked very old and his hair was white. He looked thin and weak, and his hands were shaking(发抖), but he looked very happy.

He smiled at her and said, “ Good morning! Lovely day, isn’t it?”

He had a big smile on his face, and his eyes showed his happiness. But Alice saw that he had no teeth.

“Good morning!” said Alice. “Yes, it’s a lovely day.”

Alice thought he was old and clever. She thought he must be more than 90 years old. She wanted to ask him about the secret of a happy old age.

“Excuse me. But what is your secret for being so happy at your age? I hope I can look as happy as you do when I am your age.”

The man in the chair said, “My secret for happiness? I smoke every day, and drink three bottles of wine every day. I eat hamburgers, I eat chocolate and I never eat vegetables. I never walk anywhere and I never play sports. I sit and watch TV all day.”

Alice couldn’t understand. She wanted to know how the man got to be so old when he did everything wrong. She thought he should be sick and unhappy. Perhaps she was wrong. Maybe, she thought, people could live a long happy life without eating well and doing lots of sports. 

“How old are you?’ she asked.

“It’s my birthday today.” Said the man, “I am forty-seven.”
