John Cena says thinking about death helps him make a bad day shorter

John Cena says people should talk more openly about death.

Noam Galai/FilmMagic John Cena has a tip for making a bad day feel shorter.

The retired wrestler says remembering he's "just renting" helps him appreciate being alive.

The thought helps him see setbacks and frustrations in a different light.

John Cena , 49, has a trick to put a bad day into perspective.

During an appearance on " The Drew Barrymore Show ," the retired WWE wrestler spoke about how getting older has shifted his perspective on life.

When host Drew Barrymore said turning 50 helped quiet her negative self-talk because she realized she had less time, Cena said he, too, had a similar epiphany.

"We're all going to die.

And I don't think we look at that enough, because death — loss — is tragic.

It's morbid.

It's very sad if you look at it that way.

It is absolute and inevitable," Cena told Barrymore.

Cena said science may one day extend life or help people avoid the pain of loss, but for now, he sees death as an unavoidable part of being human.

People would be "much better off" if they were able to have open conversations about death, he said.
