What nonsense. He ring-psychology and timing were exceptional. Seriously, if you can name me another performer who has done what he has, can do what he has, or is doing what he has, then I'd like to hear it.
And yes, his age has meant he takes longer to recover, but when he was called upon (the last two Wrestlemanias spring to mind) he turned on the class as only he can. I hope he has a good retirement. I'm glad I got to see him at his absolute peak.
