Meet Tatiana and Krista Hogan, a set of 2-year-old twins conjoined at the head. Like most conjoined twins, they share bone, veins and arteries, and in this sense, they share a brain. But their mother believes that because they share a thalamus, each girl can actually see and feel what the other is doing. National Geographic follows these little medical marvels to get an intimate look into their lives. Watch the Hogan family attempt to live as normal a life as possible.

How our DVDs and DVD-Rs Differ
Customers who purchase programs in the NG DVD Exclusives Library will receive a non-interactive, play only disc. There is no chaptering information on these DVDs, but there are chapter marks approximately every five minutes, which make it easy to fast forward through a program. The DVD-R format provides the digital video and audio quality you expect from all of our DVDs.
NOTE: The NG DVD-R titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
