It’s not like there are people checking for immortals, I think it would be flagged by a dmv employee or something when they dont believe a clear 21 year old is actually 150. Let’s assume it’s current day im caught and not bring speculation on what the US is like in the year 2139 is like.
in the number industry we call it a transposition error and you can tell if the difference between the two is a multiple of 9.
All I can think of is a gruff, blue collar worker coming home, covered in oil stains. He hangs up his hardhat and lunch pail at the door. “You would not believe the day I had!” He says, “Some jackass put the 9 dies in the 6 press, and I had to spend all morning trying to pry open the hydraulics without fucking them up. After all that, I get a call that the serifs are too long on the ones and they’re getting sorted as sevens!”
Never would have thought of that.
