UFC women's bantamweight champion Ronda Rousey has yet to suffer a loss in her mixed martial arts career, she said she'd rather die than ever have to experience the taste of defeat.

"With Liz Carmouche, I thought I could die for sure," Rousey said during an appearance on 'Jim Rome on Showtime,' according to MMAFighting.com. "I blocked a choke so she turned it into a neck crank. I felt my jaw dislocate and I was thinking I would rather break my neck than lose this fight."

Rousey is currently 10-0 in her four-year career. She is set to defend her title Jan. 3 against top contender Cat Zingano at UFC 182. Many believe Zingano will be the toughest test to date of Rousey's career, but the women's bantamweight said her motivation not to lose gives her an advantage over any opponent.

"Have you ever lost in the Olympics? I would rather die than lose," Rousey said. "I know that feeling so well. It's not that I've never lost. I've lost at the worst time so I know what a loss is. That's why I want to win so much more than these other girls. It feels like dying to me. I'd rather die."

Rousey also revealed she thinks about life after MMA a lot and the thought of retirement scares her.

"That's one big worry of mine," she said. "There are so many people out there who fight too long. I don't know how I'm going to deal with it. I tried stepping away from judo, and I've never been so depressed and lost in my whole life. I want to be able to step away and step away for real. When I retire, I'm going to retire forever. I'm not going to be that person who comes back. I don't know how I'm going to handle it. That's one of the things I'm actually scared of."
