Alicia was a young woman who liked to exercise for her health. In fact, she walked five kilometers before    26   every morning, and went swimming once a week at the swimming pool. She didn’t smoke and never    27   . She didn’t eat chocolate. She didn’t eat sweet and fatty food,    28   . She weighted herself every day.

One day Alicia was on her daily walk when she saw a    29    sitting in a rocking chair under a tree. He looked very old and his hair was white. He looked thin and weak, and his hands were shaking,   30    he looked very happy.

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

He had a wide smile    31    his face, and his eyes shone with happiness. But Alicia saw that he did not have teeth.

“Good morning!” replied Alicia. “Yes, it is a lovely day.”

Alicia thought he    32   very old and wise. She thought he must be at least 90 years old! She decided to ask him about the    33    of a happy old age.

“I hope you don’t    34    me asking,” she said, “but what is your secret for being so happy at your age? I hope I can look as happy as you do    35    I am your age.”

The man in the rocking chair said, “My secret for   36   ? I smoke twenty packets of cigarettes every week, and drink three bottles of wine every day. I eat hamburgers and chocolates whenever I want. I never eat vegetables. I never walk anywhere and I never play sports. I sit at home every day.”

Alicia was    37   . She didn’t expect the man to give her an answer like that. She wondered how the man got to be so old when he did    38    wrong. She thought he should be    39    and unhappy. Perhaps she was wrong. Maybe, she thought, people could live a long happy life    40    eating well or doing lots of exercise.

“How old are you?” she asked.

“It’s my birthday today,” said the man. “I’m forty-seven!”
