#4 Vince McMahon
The Medical condition he has struggled with: Dyslexia--a mental condition in which the victim has great difficulty with written language, sometimes seeing words and letters reversed or being unable to read at all.
Vince McMahon, even in his seventies, presents a portrait of unmitigated power. A lifelong gym and fitness enthusiast, his body development is still impressive despite his advanced age. He has even appeared on the cover of Muscle and Fitness magazine, just to prove how amazing his physique really is.
He also seems to be an almost God-like figure in pro wrestling, utterly confident and having an answer for almost everything. However, not many people know that Vince has actually battled against a foe that no one saw coming; dyslexia.
Given that his job with the WWE for a long time was at the announce table--where he had to read transcripts and hawk upcoming events--it's quite astounding that he was able to perform so well, without a hitch, despite his condition. Not even dyslexia can stop The Boss!
