Some 40 pairs of identical twins met at Babelsberg Film Park in Potsdam just outside Berlin on Saturday . According to the organizers , the participants in the 21st twin meeting came from all over Germany and Switzerland , including cities like Munich , Kiel and Hanover . The youngest were small children , while the oldest were already pensioners . The idea for the annual meeting arose over 20 years ago . Siblings from a twin family in Bremen regularly visited a brother in Berlin . A spokesman for the organizers said that this led to the idea of inviting more twins . The pairs of twins also planned to watch show performances in the film park and go out for dinner together in the evening . dpa fbg si xxde wjh cro Source: The Namibia News Agency
