GAD: You're 38. Does retirement enter your mind?
DH: It's hard to know when that moment is. There's a lot of fighters going through that dilemma. Randy Couture, Chuck Liddell, it must be going through their heads. There's things I want to accomplish that are attainable in this sport, and if I attain them, it would probably be a good time to retire. I want to beat Anderson Silva (the sport's No 1 pound for pounder, who Henderson lost to two years ago) and I also want to fight for the 205 lb belt. And then retire. link
