I came across the story of Robert Shields, the guy who apparently wrote the world’s longest diary on a fleet of IBM Wheelwriters. The specific model I can’t identify from the photo.

He was a guy who logged every minute of his life, literally. For 25 years straight, he wrote down what he was doing every five minutes. Not in a casual way, either. This was a full-on obsession. We’re talking 37.5 million words stuffed into 91 boxes. The guy turned his whole existence into paperwork.

He started in 1972 and didn’t sleep more than two hours at a time—said he didn’t want to miss recording his dreams. Most days, you’d find him in his underwear out on the back porch, spending four hours writing about everything—his body temperature, his bowel movements, and whatever else popped into his head. He treated it all like it mattered.

A former minister and English teacher from Dayton, Washington, he said stopping the diary would’ve been like turning off his life. And he meant it. Some entries were deep—religious thoughts, philosophical stuff. Others were about changing a light bulb. One even included nose hair samples, preserved like they were ancient artifacts. The man wasn’t playing around. He documented the human condition down to his bodily functions.
