Undertaker, under his real name Mark Calaway, did an interview with the Houston Chronicle to promote SpurRaffle.com. In it, he's asked why he continues to wrestle despite his injury history.
"Honestly, I love it, that's why," Calaway said. "I've got 26 years in the business and all these injuries, but WrestleMania has become so huge, it's just hard to walk away from it. I want the audience leaving the stadium going 'Wow!' It's a responsibility I have being a top dog in this business. The crowd will let me know when it's time to leave. They haven't yet."
He also hinted at feeling a sense of obligation to work WWE's biggest pay-per-view of the year.
"If I didn't perform at WrestleMania, in some strange weird way, I'd feel like I was letting Vince McMahon down."
Undertaker notes that his down time is spent healing up, spending time with family and working on his "horrible golf game."
