Doctor Oz did a segment called “Extreme Medical Marvels” and brought on the tallest and shortest people in America. The shortest brother and sister in America are Bridget and Brad. These siblings have Primordial Dwarfism. Bridget is 20 years old and is 2 feet and 2 inches, weighing only 18 pounds. She weighed around 1 pound when she was born. Brad is a couple of years younger than Bridget and he is 3 feet 2 inches and about 20 pounds… and boy is Brad muscular!
