Why does "The Rock" need a stunt double?

I wan to be insurable -- and not in the life or death kinda way -- I've way to many episodes of Snapped and Investigation Discovery.

RDJ tried to do his own stunts in Iron Man 3 (the easy peasy little green-screen jumps) and ended up either spraining or breaking his ankle.

The Rock wrestled for years. I'm pretty sure he knows how to do most of his own stunts.. It's for insurance purposes most likely.

I mean he might be strong and fit, but some of those stunts probably take time and training to master. He probably could learn them if he wanted to spend the energy and effort, but he doesn't need to

What I meant when I said he wrestled is that they do a fuck ton of stunts. And if you still believe that main stream wrestling is real, I'm sorry to be the bearer of bad news. But yes, I do understand that movie stunts are more hardcore when it comes to certain ones. And I also agree he probably doesn't want to do them.
