Now retired, Mark Callaway, who was formerly known as professional wrestling’s “The undertaker” has found a new life as a real estate investor. He owns a multimillion dollar building in Loveland, Colorado called the “Calahart”. And Callaway is actually a very nice guy in real life unlike hid dark and sinister “Undertaker” character. He has helped to fund a rescue charity at Texas A&M Veterinary College, proving he deeply loves our four legged friends. Among Mark’s Facebook like pals is none other than Muhammad Ali among other people. That’s some good company there… But, the good works of this great athlete don’t stop there. He auctioned off his prize West Coast Chopper bike to a church ministry that helps our veterans through SPUR MINISTRIES in Austin. In real life, this big tough action guy is a real saint.
