The guy on the left competed on the Swedish badminton team at the recent London Olympics. His name is Henri Hurskainen. Many sports commentators noticed that he's a dead ringer for the Sedin Twins.
But Henri is 25 and the Sedins are 31, so they can't be triplets. But perhaps Henri is a long-lost younger brother? I guess only Mom and/or Dad Sedin knows for sure . . . . But if nothing else, these guys' resemblance sure demonstrates the prevalence of similar traits in the Swedish gene pool, doesn't it?
