Conjoined Twins Share a Brain

The twins' condition has given them very real problems. Tatiana, the smaller of the two, has an enlarged heart and actually pumps much of Krista's blood to her brain. The complications have led to surgeries and more worries. "We just kind of live today," said mom Felicia Hogan. "We live within today. Forget about tomorrow, we'll deal with tomorrow when tomorrow gets here." For now, the girls are healthy and strong. (Courtesy Renegade Pictures)
