Older Fighters Dominating at the Top Levels Like Never Before

With conditioning levels possibly higher than ever before we are seeing older fighters competing and in some cases dominating at the highest levels.  In MMA, you have fighters like Randy Couture and Dan Henderson in top form in their 40s while others are still peaking into their mid 30s like Anderson Silva and Fedor Emelianenko.  In boxing, Bernard Hopkins and Glen Johnson are still dominant in their 40s while you have Sergio Martinez as a consensus top 3 pound for pound fighter at 35.  The landscape is changing, fighters are no longer washed up in their 30s.  I think a lot of the credit has to go to conditioning levels being like never before.  Fighters are in great shape and take care of themselves extremely well these days.  Who knows how much longer Anderson Silva, Fedor Emelianenko or Sergion Martinez can figh at the top levels.  Regardless, don't put it past them to be great into their 40s if they wish to continue fighting at that point.  It will also be interesting to see how other current pound for pound greats like Manny Pacquiao, Floyd Mayweather and GSP will do into their mid 30s and beyond.  Not everyone agrees with this given examples from the past relating to older fighters but I think we are in a unique time period.
