World Wrestling Entertainment (WWE) Universal Champion Bill Goldberg is one the most powerful and dominant wrestler in the history of the WWE. At 50 years old, Bill Goldberg is still dominating opponents. Not only is Bill Goldberg dominating opponents, he's destroying them fast and quick during his matches. But as fast as Bill Goldberg destroys opponents, his body is also quickly breaking down. Bill Goldberg may be entertaining fans with his WWE matches, but that doesn't mean he's happy about it.

Bill Goldberg said his latest comeback to the WWE left him miserable, according to a report from Yahoo Sports. Bill Goldberg recently opened up about the toll that his body has taken while guesting on former WWE superstars Edge and Christian's podcast, the E&C's Pod of Awesomeness last week.

"I'll be honest, I'm miserable. I'm absolutely miserable," Bill Goldberg said. "Nobody get me wrong when I say I've been miserable throughout this, but I am. I'm miserable."

During the podcast. Bill Goldberg also added that he's a like a machine now because people are expecting him to be able to do exactly what he did back when he was still young. As a result, Bill Goldberg says that he's stressed out.

"I'm bloated 24 hours a day. I'm stressed 24 hours a day. I don't sleep, but it's a small price to pay." Bill Goldberg said.

Being a 50-year-old wrestler, Bill Goldberg has to adapt to a very insane diet to keep himself in shape, as reported by the New York Post. It's a sacrifice worth making according to Bill Goldberg.

Bill Goldberg shocked everyone when he returned to the WWE last October after more than ten years since he retired. Since returning to the WWE, Bill Goldberg has had three matches so far.

Immediately upon his return, Bill Goldberg defeated Brock Lesnar at Survivor Series. Then, Bill Goldberg competed in the Royal Rumble. After the Royal Rumble, Bill Goldberg dismantled Kevin Owens to capture the WWE Universal Championship.
