A lot of dumb and ignorant comments in this thread. Ken took a lot of damage in the second half of his MMA career--just look at how many fights he lost via TKO. But all of that also ignores the brutal training that characterized his MMA career (sparring at the Lion's Den was basically live fighting) and all of the other stuff he was into before MMA--street fights, wrestling, Tough Man, bouncing, football, etc. He also had a lot of issues with drugs, so yes, I'd say he's amazingly lucid given his career and life. That, and physically he looks very good, whereas Frye looks and sounds like a guy who, sadly, will probably not live much longer. Severn sounds about the same as he always has. I assume he always has and still does take care of himself.
