If you think Kim Kardashian or Rihanna were the ultimate selfie takers, think again. We've found a new contender for the crown.
Meet Karl Baden, a 61-year-old photography professor who has been snapping pictures of himself everyday since the 80s.
He then complied the 24 years and eight months of photos into a fascinating two-minute time-lapse video.

Karl's 'Every Day' project is an exploration into the role that mortality plays in our lives and how age affects our appearance.
He claims to have only missed one day, when he was running late to teach a class in 1991.
Speaking to Boston magazine, he vowed to only stop snapping once he's dead. He then plans to have his work displayed in an institution.
