The doppelganger used to be an almost mythical sort of idea. That somewhere out there, there existed another human being that through sheer luck or fate looked exactly like you. Movies and books told many a tale about coincidental meetings between two unrelated twins, and as you can imagine, hijinks would usually ensue.
But thanks to the Internet, facial recognition technology, and clever entrepreneurs, there are now easy ways to find your own doppelganger, and maybe go on some film-worthy adventures of your own. Of course, there’s still a fair bit of luck involved, but sites like TwinStrangers.com certainly make the odds a little less astronomical.
