"I think you can see me fighting for around six more years. I love what I do. The team that works with me does a fantastic job. I've never had a serious injury that took me away from competition. So I think I'll be at this a little while longer." -Anderson Silva via Estado

At 37-years old, most professional fighters have either already hung it up, or they are at least looking at gearing things down and preparing themselves for life outside of the cage. Anderson Silva though, is not "most fighters."

The dominant UFC middleweight champion hasn't lost a fight in almost seven years, a span of 16-straight victories, and he doesn't see the need to slow down anytime soon.

Silva (32-4) has been relatively healthy throughout his career. He has suffered through shoulder and back issues and required surgery for an elbow injury a couple years ago, but that's small fries considering the amount of time he's been in the sport and how many professional fights he has under his belt. 

His style and physical skills, notable his ability to quickly duck and skrikes have surely prolonged his career as well, as it's rare to see him take punishment in the cage. 

Silva, who recently turned down a fight against hard-charging up-and-comer Chris Weidman, citing a lack of interest in the fight, has been lobbying hard for a "superfight" with fellow long-time dominant welterweight champion Georges St. Pierre.
