Transcript:

Welcome to this week amazing life. To start with this week, we are looking at the life of a French woman called Jeanne Calment. Jeanne Calment was born on the twenty-third of February 1875 in the town  of  Arles in the south of France and she spent all her life there. She lived a very quiet life in her hometown and she only became famous in her later years. And why did she become well-known? Because she lived to a very old date. At the age of 113 in 1988, she became the world oldest living person. And she continued to live for a long time after that. She said she lived for a long time because she ate very healthy food. But she also likes chocolate, and she ate a lot of chocolate every week. She was also famous because she met the well-known artist Vincent van Gogh when she was 13 years old. And at the age of 114, she appeared in a film called Vincent and me. It was about the  life of a famous artist. Jeanne Calment died on the 4th of August, 1997 at the age of 122. At that time she was the oldest living person ever.
