Mark Calaway, a.k.a. The Undertaker, has been wrestling for a long, long time. He signed with the WWE in 1990, so he's now in the middle of his third decade of professional wrestling, which has certainly taken a toll on the now 50-year-old's body. Back in August, after participating in one of the WWE's biggest events, SummerSlam, The Undertaker reportedly collapsed following his match with Brock Lesnar. For the past few years, many thought his retirement was imminent, but one of the most notorious wrestlers in WWE history continues to prove them wrong.
Case in point: this recent workout video of The Undertaker, in which the old man hits a Box Jump of 40 inches and deadlifts a whopping 500 pounds. When most normal human beings hit the half-century mark, they read the newspaper, stir lemonade and reminisce about the good old days, when Tweeting was less important than interacting with your family.
The Undertaker: Still completely terrifying at 50 years old.
