Conjoined Twins Share a Brain

For their grandmother, Louise McKay, the twins have been nothing short of a miracle. "No one would ever believe that I used to be a woman who couldn't come out of her bedroom," said McKay. "I had [a] panic disorder so bad that to do the everyday things was impossible. Until they came along. ... I knew that [the twins' mom] Felicia was going to need me, and they were going to need me, so I had to pull myself together." (Courtesy Renegade Pictures)
