Viet and Duc Nguyen
Viet Nguyen (, February 25, 1981 – October 6, 2007) and Duc Nguyen (, born February 25, 1981) were a pair of conjoined twins born in Vietnam and surgically separated in 1988. Viet died in 2007 of natural causes. Viet and Duc were born on February 25, 1981, in Kon Tum Province, Tây Nguyên, Vietnam. Viet was the elder and Duc was the younger of the two brothers. Their relatives claim that "the reason they became conjoined twins is the influence of Agent Orange that the U.S. military used as a defoliant during the Vietnam War". His mother was  farming in the area doused with Agent Orange a year after the Vietnam War had ended. She also drank water from a well in that area. After that, Viet and Duc were born. On October 4, 1988, Viet and Duc were separated in the hospital in Ho Chi Minh City with the help of the Japanese Red Cross after Viet went into a coma. Duc first entered junior high school, then dropped out and learned computer programming in a school. Now, he works at a hospital in Ho Chi Minh City. On December 16, 2006, he married Nguyen Thanh Tuyen  in Ho Chi Minh City. Viet's health problems continued after the separation, and he died due to liver failure and pneumonia on October 6, 2007, at the age of 26.
