Lulu Gribbin survived a near-fatal shark attack in 2024.

CNN Video(CNN) - In 2003, when Hawaiian surfer Bethany Hamilton was just 13 years old, she lost her arm in a shark attack while surfing in Kauai. Her positive approach has also given her a unique perspective on life after the attack. She won the National Scholastic Surfing Association National Championship for the 18-and-under age group in 2005. Her unique journey and positive perspective has inspired people around the world and has now manifested itself into a documentary, 'Bethany Hamilton: Unstoppable.' As good a surfer as Hamilton is, she is not immune to wipeouts, but every time she gets knocked down, she gets back on her board.
