With all this discussion about Brock lesner recently, Lesner was going to fight Hong Man -Choi in MMA. Although, Man Choi was not medically cleared to fight in the USA because of a Tumor on his pituitary glad. Lesnar fought a poor replacement. Basically, Man Choi has a medical condition that causes his extreme height. His parents are probably 5'3.
He suffers from acromegaly. The same condition that Gheorge Muresan had of the Washington Wizards.Its an over stimulated pituritary gland.Hence his enlarged mandibles and size aswell as the tumor/cancerous growth on his pituritary gland.
