A professor at Boston College has taken a black and white photo of himself everyday for the past 30 years to document his aging.
The 64-year-old man started the project on February 23rd, 1987, well before the word “selfie” became popular.
He has kept the same expression and used the same lighting for each photo.
He’s also not grown a beard or mustache or changed his hairstyle much.
The professor plans to do the project for the rest of his life.
