“[Robert] Reich is 4 feet 10-1/2 inches (149 cm) tall. His height is a result of multiple epiphyseal dysplasia, also known as Fairbanks disease. This genetic condition has also affected Reich’s hips; he had double hip replacement surgery in 1992.[6] Reich has used his height as a source of humor, once appearing with the 6 ft 4 in (193 cm) Conan O’Brien in a sketch on Late Night with Conan O’Brien.”
