While swimming off the coast of Hawaii in Maui, a woman was attacked by a 12-foot tiger shark. Luckily, the woman remained calm and used her black belt in taekwondo to escape the attack by punching the shark dead in the nose. “My Tae Kwan Do prepared me to learn how to punch,” she said. “I punched it twice. I punched it this way, and that one contacted. But this [punch] kind of hit the side and slid into the mouth.”
The blows were enough to scare the shark off, and the woman escaped with wounds that required 100 stitches on her right hand and thigh. Considering the fact that she escaped with her life, that's a small price to pay.
