I hate Cena the character, but respect Cena the man and worker. He works his ass off, love him or hate him. He's had a lot of injuries already, performs through many of them, and his body is clearly ballooned on steroids. I'm curious to see how hr ages. Maybe he doesn't party like most other wrestlers and it'll keep his condition from falling off a cliff. PEACE.
Cena doesn't party - He has no life outside of WWE. He eats, drinks, sleeps, shits, and breathes WWE.
When he was filming some of his movies, here is more or less how his Monday was (2 hour RAWs back then)
3:00 AM - Wake up.
5:00 AM - Filming starts
12:00 PM - Filming stops,
12:00 PM - 5:00 PM - Make a Wish work (includes air travel)
5:00 PM - 8:00 PM - Plane to WWE event location and preparation
8:00 PM - 10:30 PM - RAW + overrun
Then he'd get back on a plane and travel to the filming location, getting a few hours of sleep on the plane and in his hotel.
If he is booked to bury Wade Barrett under a pool of chairs, that's what he'll do. No questions asked. If he's told to fly to 3 or 4 different cities to wrestle, film movies, and do Make A Wish work, he'll do it. If his marriage and friendships outside of wrestling are weighed against being a WWE corporate slave, he'll choose WWE, always.
