At least once every day, as a motivational tool. I even created a spreadsheet that tells me how many days are left for me to live, and what percentage of life is already behind me (based on the projection from a bunch of actuarial tables).
That wouldn't work for me -- it would sound like plenty of time to me¹. (And that would happen regardless of what unit I² used -- 1,500,000,000 seconds? That's a lot of seconds! 50 years? A year is a helluva long time! 600 months? Why would you² use months of all units, are you² trying to fool me¹ or something?)
i.e. my System 1/elephant.
i.e. my System 2/rider.
This is a thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. The previous "stupid" questions thread is at almost 500 questions in about a month, so I think it's time for a new one.
Also, I have a new "stupid" question.
