Well, getting in the wrestling, you kinda know what you're getting yourself into. It's no secret that wrestling takes it's toll on your health with travelling, taking bumps and all the painkillers involved.
What confuses me a bit; I just read the breaking news that Punk signed with UFC. But earlier this week in the Art of wrestling podcast he complained about receiving stiff shots by the likes of Ryback. So... wrestling is "fake" you take a few nasty hits and hate someone for it, but decide to sign for actual combat sports.
Don't get me wrong, I really liked CM punk during his WWE run. His pipebomb promo was the best thing in a while.
