Progeria – the ultra-rare condition that causes sufferers to age too fast – has featured in some of Born Different’s most memorable episodes. And now, for the first time, we’ve collecting some of the most inspiring stories into one special documentary. We meet siblings Michiel and Amber Vandeweert, aged 20 and 12 respectively, who love go-karting and dancing; and Challi Muguira, 30, and Tiffany Wedekind, 41, who are two of the oldest survivors with the condition. And last, but most definitely not least, we revisit one of our most popular ever characters, 11-year-old Adalia Rose who is so popular on YouTube that she’s amassed over two million subscribers. Amazing people that we are proud to feature - we hope you enjoy watching these wonderful, inspiring films as much as we enjoyed making them.
