Have You Been Told You Look Just Like Someone Else and are Doppelgangers Real? [VIDEO]

I'm sure in your life you've been told you look just like someone else, or perhaps you've seen a stranger who you thought looked just like someone in your life.  I remember at least twice where a stranger walked up to me and said I looked just like someone else they knew.  The common term is doppelganger, but can they possibly be real?  Can there be someone out there that looks exactly like you?

I found this video on the subject which sheds some light on the subject.  Have you been told you look like someone?  Share your story below.
