Ronda Rousey is arguably the most important fighter—both inside and outside of the UFC—on the planet right now. So the last thing on her mind should be retirement.

But during her appearance on The Joe Rogan Experience podcast on Monday, Rousey readily admitted that she's not going to fight forever. In fact, the 28-year-old—who will turn 29 in February—revealed that she is probably only going to fight for another year or two before calling it quits.

"I'm not going to be doing this in my 30s," she said. "I don't want to be fighting in my 30s. By 30s, I mean 31, 32. If you're actually 30 years old, that's 30, not 30s. Once you add the one, that's 30s. I'm 28. I don't know."

Rousey went on to say that, before she retires, she wants to take on Cristiane "Cyborg" Justino.

"It just seems unfinished—my career, there's more left to do—I don't feel like I'm done yet," she said. "With the Olympics, it's just like you win an Olympic gold medal and you're done. With the UFC, when am I really done? I'm not. It feels unfinished still. [The 'Cyborg' fight] definitely would [help]."

That fight would help her cement her legacy further. But regardless of whether it takes place or not, why is Rousey already discussing retirement? She's just now finally starting to get the recognition she deserves, so the R word should be the last thing on her mind.
