My, how time flies.

Karl Baden, a photography professor at Boston College, has made a very cool time-lapse video in which he ages nearly 25 years in about two minutes.

He maintains the same blank face in almost all the photos and essentially looks the same, except for a brief spell in 2000 when he lost his hair while battling cancer.

Baden, 61, took the photos of himself for the project, dubbed Every Day, making him something of the grandfather of the selfie movement. He began the project in February 1987 and kept snapping until November 2011, with only one day missed during that entire span.
