I got word from a colleague at a conference that my doppelgänger was afoot. Next time I went to the same conference, I met him and we took pics together. As I was watching him give his talk and he was in profile, it was really strange to feel that totally looks like me up there. Chilling.
I got mine from my mom when she was in Abu Dhabi, she cannot believe her eyes when she sees him, she said even his mannerism is mostly the same as mine. The guy seemingly disturbed by my mom's observation and left the place.
One look at the picture provided convinces me that one's chances of finding one's Double, even in a see of millions of people, is probably negligibly small. Those people are not "dead ringer"s for each other.
Pictures aren't sufficient, mannerisms and facial expressions count for a lot. I know two people who have dopplegangers identified; superficially similar in appearance but get them talking and it's really striking.
Seems like something that would be solvable by technology. Facebook has a dataset of what billions of people look like, they could probably find 2 or 3 who look exactly like me
That would be amazing (but also incredibly creepy). It would also probably end up finding a lot of people who actually are related and don't know it (adopted children etc)
