John Cena recently did an interview with GQ.com and here is an excerpt about his WWE career:
Do you ever miss the touring lifestyle of wrestling full-time?
“I miss it every day. Every single day. But I’ll be 45 on April 23rd, and I was very fortunate to make it as long as I did with only a minor list of injuries. Nothing that has changed the trajectory of my long term health. I’m strong, flexible, and in really good shape externally, internally. I think now, being a full-time touring performer might start to hit that point of diminishing returns, and I have to be realistic when I look at that.”
