At 32, Serena Williams has reached the age where many tennis players begin to see a dip in their skills.

Although that's a little laughable considering she's been No. 1 in the world for the last 36 weeks in a row.

As Williams prepared for this week's WTA Championships, she was asked by an interviewer where she saw herself in 10 years' time.

"Who knows? I might be here. I have learned from 10 years ago. I can never say," she responded.

The idea of Williams playing into her 40s isn't entirely preposterous. Martina Navratilova played competitive singles until she was 38 and Japan's Kimiko Date-Krumm continues to defy the odds and is active on tour, celebrating her 43rd birthday three weeks ago.

If she were to play even another five years, Williams could be considered a threat to catch Steffi Graf's Open Era record of 22 Grand Slam singles titles - Williams is currently at 17, also trailing Navratilova and Chris Evert by one.

If Williams were to solely focus on that record, she could play fewer events and concentrate on the Slams, relying on her own relentless will to win combined with the inevitable slew of upsets and injuries that happen every year.

Of course, even a player with Williams' remarkable combination of physical attributes can't stay young forever. Eventually, her body will break down and she'll lose a step or two of quickness, which will reduce her effectiveness significantly.

In addition, Williams has been quite fickle at times in her commitment to her craft, gone from the game nearly a full year, officially due to injury, in 2010 and 2011, but seeming to be furthering the Serena Williams brand quite a bit with products and appearances during that time frame.
