Intertwined Lives - Check out video of convention of identical twins

One theory is that all of us, yes I mean ALL OF US, really are identical twins.

What happens is that at conception there are always at least 2 foetuses who start out in Mom's womb. For most cases, however, similar to the case of chicks in a bird's nest, one of the foetuses starts to garner more and more of Mom's bounty, and in most cases the 2nd and additional twins wither and die.

Documented cases of this are seen in bird's nest, even to the extreme wher the dominant chick will peck its competing sibling chicks to death or push them out of the nest altogether to die.

In humans, this theory goes, except in the relatively rare case of twins and mulitple births, those of us who are born as single births emerge from the womb alive, having, yes, caused the death of our twin.

It is a well known phenomenon among twins that when one twin dies, the surviving one mourns terribly, and usually dies also fairly quickly thereafter.

 Something of that persists in all of us who are single births. We know in our heart of hearts that we really had a twin once, and we cannot forget him or her, and we mourn for our lost twin. When we are feeling sad and depressed, something of that is going on.

 We long for our twin. And that is why we seek a mate to marry. We are looking for our twin in our spouse. Sometimes this works, and sometimes it doesn't. But we are searching for our lost twin, who we sometimes also call our "Doppleganger", a German word signifying "double companion", or maybe soul mate.

What does all this lead to. Well, people, it is all about the twins, and the shared genes. So if or when anyone has the opportunity to meet or get to know, a person with whom they closely share a gene pool, a father, a mother, a sister, a brother, then is it any wonder that we will go to the ends of the earth to meet them. And so we should. We are naturally attracted to our gene moms, dads, sister, brother, and we love them innately.

We've all heard highly romanticized stories about identical twins, like twins who've been separated at birth only to grow up leading remarkably similar lives, or twins who can sense when the other one is in danger. But what's the opposite side of these stories? What are the experiences of twins who become weary of constantly being confused with their identical twin? How would it feel to share 100% of your DNA with someone else and be pressured by everyone to perform the same in school, in sports, and in various other aspects of your lives? Intertwined Lives explores the lives of five sets of identical twins, all at different stages in their lives and relationships, to answer these questions./Ben and Nathaniel Ludewig (both 10 years old) remember believing they were one person, named "Bendanno," when they were younger--although that hasn't stopped the two boys from fighting like cats and dogs. But, as people get older, more things start to factor into their lives and things get a bit more complicated and sometimes bittersweet./ Inseparable, Ruth and Rachel Sandweiss have lived together for most of their lives. Rachels' recent engagement, though, has created a difficult moment in their relationship. Now, the two women wonder what life will be like no longer being able to spend all of their time together. At the opposite end of the spectrum, there are AHNA and IRENE FERTIK, who chose to spend 20 years of their adult lives completely separated from each other (living on opposite coasts of the US). They thought that this would be good for their lives, since they wouldn't be there to constantly influence each other's decisions. But, even with all that time apart, the two still haven't found a happy medium in their relationship./ In a similar vein, PAUL GOLDSMITH, for several years now, has been estranged from his twin brother, Aaron. When asked, Paul says he feels as though having an identical twin robs one of their identity. So, let's face it: some twins love being twins, and others absolutely hate it. But, in the end, it's the close bonds and the constant competition twins have in their intertwined lives that defines not only their relationships, but also their identities.
