Dayton conjoined twins featured in

In 2014, Ronnie and Donnie Galyon celebrated not only their 63rd birthday, but also their new achievement as the world's oldest conjoined twins--beating the previous record held by the twins Giacomo and Giovanni Battista Tocci from Italy. The twins are joined at the waist and face each other. With four arms, four legs, and separate hearts and stomachs, they share a lower digestive tract, a groin, genitalia, and rectum. The Galyon twins were born in Dayton, Ohio, in October 1951, and they've stayed as one ever since.
