When a would-be thief approached a woman standing alone outside her Rio de Janeiro home this year, he didn’t know how unlucky he was.
That woman was none other than 27-year-old, mixed martial arts fighter named Polyana Viana, currently competing in the ultimate fighting championship. She threw two punches and a kick. He fell, then she caught him in a rear-naked choke, and sat him down in the same place to wait for the police.
