Extraordinary life ... Ronnie, left, and Donnie share a home in Dayton, Ohio
When Maureen Galyon gave birth in 1951, she had no idea she was expecting two babies - let alone conjoined twins.
The tots, joined at the torso, were not expected to survive the night as baffled doctors tried to work out if they could be separated.
Now, at 57, Ronnie and Donnie are the world’s oldest conjoined twins and have amazed the medic world by hanging onto life for so long.
And, as their health declines and they near their dying days, the pair have opened their doors to a documentary team to reveal the secrets of their extraordinary life together.
Although every day is a struggle as the men have to coordinate the simplest of tasks, they have a close, loving relationship and are able to live together in their own home in Dayton, Ohio.
The affectionate documentary, Extraordinary People: The World’s Oldest Conjoined Twins on Five on March 18 at 9pm, will bring hope to British mum Lisa Chamberlain who is expecting conjoined twins as it shows it is possible for the babies to not only survive but to live a happy life.
