The Undertaker retired at Survivor Series 2020
"It’s pretty rough most mornings. It takes a while to get things moving.
There has to be that initial assessment when the feet hit the floor in the morning, you know, what’s hurting? What do I need to kind of bring along a little slower than everything else? So the first thing I do is assess.
It’s such a strange thing after all the years and all the matches and all this, it’s like I have to sit there and figure out how on Earth - because I’ll wake up some mornings with something hurting that I had no idea that I’d strained, pulled, whatever - and I’m trying to figure out, “How did you hurt yourself sleeping?!”...
That comes with the game. The human body is definitely not made for the abuse that professional athletes put their bodies through. Especially football, hockey and wrestling. I mean, all sports, but the high-impact sports, the body is not made to do that" - The Undertaker stated.
