siamese twins

Siamese twins refer to a rare medical condition also known as conjoined twins. This condition occurs when two individuals are physically connected to each other at birth. They share certain organs and/or body parts, which can vary in severity and location depending on the specific case. The term "Siamese twins" comes from Chang and Eng Bunker, the famous conjoined twins from Siam (now Thailand) who gained international attention in the 19th century.
