Frida Kahlo was born in Mexico in 1907. When she was six years old, her life changed completely. She got a serious disease called Polio, and had to remain in bed for nine months. The disease made her left leg shorter than her right, and she had serious problems in walking.
    When Frida was 15, she was enrolled at a prestigious school in Mexico City. There she was influenced by the modern changes that were sweeping across Mexico.[22]She cut her hair short like a boy and started riding a bicycle — shocking for a young woman of her time. She was very interested in science, and decided to become a doctor.
    Then, in September of 1925, Frida was involved in a horrendous accident. She was riding on a bus when it crashed into a trolley car. Her right leg was broken in 11 places. For the rest of her life, she had severe pain every day caused by that accident. She had to give up her plans to become a doctor, because she knew she would never be strong enough. While lying in bed after the accident, Frida began reading books about art. Her father was a painter and photographer, and he encouraged her interest in art.[24]One year later, she completed her first painting: a portrait of herself.
    Over the years, Frida Kahlo painted more than 200 pictures.[25]Most of them were about very personal subjects — her health and her dreams. She also used many bright colours and symbols from Mexican culture. Frida died in 1954, at the age of 47, but her paintings still fascinate people. In 2002, a popular movie was made of her life.
