The Tulsa World reports that a 75-year-old woman in Moore, Oklahoma, fought off a 35-year-old rapist by kicking him in the groin, poking him the eyes, and hitting him on the head with a cordless phone.
According to the news report, she apparently picked up a few fighting techniques from watching Dr. Phil! I tend to be skeptical about what someone can learn from watching TV, but it apparently helped in this case.
It's just a short news report, but I would assume the rapist wasn't armed. I suspect the woman read the situation and instinctively knew she'd be safer fighting back. And she didn't let the fact that he was half her age get in her way.
