The Undertaker's whole shtick is that he's undead and immortal in a certain sense, but considering how well he's held up over the years and countless beatings he's taken --and somehow continues to take -- as compared to other pro wrestlers who have come and gone, there may be a bit of truth to the whole immortality thing he plays up in the ring. Seriously, dude's 46-years-old, has been battling within the squared-circle since 1984, is an eight-time WWE Champion, has probably suffered every injury in the book, and still manages to hold his own against the young bucks in the WWE -- whatever The Undertaker is doing, he should bottle and sell it!
