You've taken very little punishment during your career, but at age 35, how much longer do you anticipate fighting?

"I plan to end my career when I am 37 but we will see how I feel then too.

"At 35, I am in the best shape of my life. I'm dedicated to my craft and to the sport of boxing. For those reasons, I know that as long as I feel and remain healthy, I can continue to fight for as long as I want. I have the best team, "The Money Team," in my corner who works with me day in and day out to make sure that I'm prepared every time that I step into the ring. Staying focused is definitely a big part of my success and it will continue to be. At this moment, I'm the fighter to beat and I don't see that changing anytime soon.

"Of course, I would like to fight for the fans too. They have supported me throughout my career and without them I would not be the fighter I am today. Forty-two have tried, 42 have failed. I will hang up the gloves when I'm ready.

"When my career is over I know I will live with no regrets. Everyone asks about other fights and fighters I might fight but none of that will affect my decisions to fight moving forward.

"I don't live with regrets. No way. I work for me, I fight for me and I will always do what's best for my career and my family. But right now, I'm focused on my upcoming fight with Miguel Cotto on May 5 and once I beat him, I can then worry about what's next step in my career."
