John Cena has returned to the WWE, and for a longer period of time than many fans thought. The wrestling legend-turned-actor is currently on the road for his Summer of Cena tour, which will culminate at SummerSlam 2021, where he will face Universal Champion Roman Reigns. It's unclear where Cena will go after that, though the star of The Suicide Squad recently gave some big-picture thoughts on when he thinks he'll be ready to retire from the WWE.

Returning to WWE, it's a brand new world. A new cast of characters, new direction with the company, new platforms, new environment. There is a challenge there. To challenge myself as a 44-year-old to go back, there is an intrinsic challenge there; there's a different set of circumstances there. That's a good challenge in many ways. My body could tell me after this extended stay, 'Dude, you're done' or it could tell me, 'You're so far from done it's crazy.' That's another interesting conversation with myself. If I get physically that I'm slower, I've said openly to everyone that I'm gonna keep doing this until I feel I'm offending the customer. I will continually go out there and do what I can to contribute and add. I don't want to go out there and be like, 'Okay, just let him go out there and (do his thing).' I'm not into that because I know what it's like to pay for a ticket. If I were to get that on this go-round, it's a humbling and tough thing that I'm gonna have to hurdle. If I get the opposite and it's like, 'You're quicker and can do some things better and coexist and define a new personality,' then that's a new conversation because I do not have much time left and if I want to give it like, 'Let's really commit to this thing and really go all in,' that's an honest choice where other stuff will have to take a backseat to.”
