Okay, I have done a lot of research on this subject. Here is what we know to be FACTS:
* Troy Aikman was always listed at 6'4" by the Dallas Cowboys
* Hulk Hogan was listed as 6'7" for most of his adult life
* Hulk Hogan specifically told Larry King that he currently stands 6'4"
* Hulk Hogan specifically told Larry King that he stood 6'7" until he had several surgeries on his back where several discs in his spine were removed.
* A cartilage disc in the human spine of an adult male is approximately one inch thick. Each time a disc is removed, it is replaced with a sheet of metal that is as thin as a piece of paper. In other words, each disc you lose costs you one inch of height. I know this is true from personal experience because my cousin was in a motorcycle accident where he needed two discs replaced, which caused him to lose two inches of height. My cousin ended up 6'2" even though he previously stood 6'4". A similar situation happened when a friend of mine was in an auto accident; he also lost two inches of height because two discs were removed.
* Lou Ferrigno was listed as 6'5" when he was cast as an actor on The Incredible Hulk
* Lou Ferrigno currently stands 6'3.5" tall
* When Hulk Hogan and Lou Ferrigno stood next to each other when both were in their prime, Hulk Hogan was noticably taller
* Arnold Swarzenneggar was measured at 6'2" when he applied for the job on The Incredible Hulk. It was specifically stated that the reason why Arnold was not selected was because of his height.
* Dwayne Johnson was listed as standing 6'5" by the University of Miami Football team.
* When Hulk Hogan wrestled The Rock (Dwayne Johnson) it was obvious that Hogan was taller
* There are times in the Rent-a-Center commercial when Hogan stands equally tall next to Troy Aikman, and others when Hogan appears to be slightly shorter.
* Hulk Hogan currently has severe back pain as a result of multiple back surgeries. This causes Hulk Hogan to occasionally lean forward, which costs him up to one inch at times.
Bottom Line: Hulk Hogan really was 6'7" for most of his adult life. And we know that Lou Feriggno was 6'5" when he was cast to play the part of The Incredible Hulk. These two issues are not debatable.
