5 reasons why John Cena could retire in 2020

#4 Age

How old is too old in this game?

It seems a bit odd to suggest that John Cena is getting too old to do this, especially given the fact that Edge recently returned at the age of 46.

However, we don't really see all too much point in bringing on someone who is about to turn 44 and putting them back into a full-time schedule. We know that there's the option of him going part-time, but again, having him come back and take spots from others simply isn't fair and the man himself has even been quick to admit that.

Plus, while ring rust may not be a 'thing' for a lot of wrestlers, Cena hasn't exactly been active as of late. It's been over a year since he was in the ring in an official capacity, and he needs to be performing much more regularly if he wants to hang with the big boys.

Cena needs to be preserving his body for his new career as opposed to an industry that he's already been able to thrive in for so long.
