We're fast approaching 7:41. The latest in our series on overcomers. Triumph over tough challenges that life can throw at us all. Two young women, Emily and Caitlin Copeland, they were born conjoined, kept it a secret for a long time, this morning, they're sharing this remarkable story on this their 18th birthday. You'll see this only on "Good morning amica." They're as close as two sisters can be. I like growing up with her, she's fun. Reporter: Emily and Caitlin Copeland, 18-year-old conjoined twins, who can share an easy laugh, a bond few can ever imagine. Emily and Caitlin were born C conjoined.
