I just realised that the oldest file that I have used continuously on my computer is now 20 years old. It’s a spreadsheet called “Boring” that was in use before 2004 on a Psion organiser.

@BestofTimes Following the link led me to learn about tetraphobia.

@BestofTimes well now I just want to know what could possibly be so boring if you’ve kept up with it for 20 years.

@Contrariwise my wife and I refer to the bank account that covers day-to-day expenses and bills as the “boring account”. This spreadsheet keeps an eye on those expenses. 😂
