When Hannity asked him about his poor early debate performances, and what he would have done differently, Perry said he really underestimated the effect the back surgery would have on him. He said he's running up to 15-20 miles a week and feels much better.
FWIW.
I missed the Hannity interview so thank you for those details.
Yes, Perry’s debate performance began to improve when he was able to run again!
Exercise is good for the body, mind & spirit!
