Great Documentary About Twins

Just stumbled on this today, wish I would have found it months ago.  Its a really good documentary about twins and multiples and how they come to be.  It explains a lot of things we have learned over the past 7 months and in really easy to understand terms.  Be forewarned, its a full fledged documentary, every bit of an hour and a half long so if you really are interested in learning about it, make sure you set aside some time for it.
