23-year-old conjoined twins share their experiences on what it's truly like to share a body

They took their first steps age four, but only after receiving years of physical therapy to teach them how to sit up and control their legs as a pair. Despite the arduous journey they've had over the years, surgery has never been an option for Carmen and Lupita as the risks are too high and it could be fatal for one or both of them. "If we had separation surgery, either one of us would die, both of us would die or we’d end up in the ICU and never get out," Lupita shared.
