I did something similar, but in reverse. Rather than give myself an arbitrary "death day", as the author did, I instead chose to make a life clock. It's just a display of my age in years, months, days, and seconds. The advantage of this is that it is 100% true. There are no mental tricks you can play. Things like: I know my clock says 8500 days, but I'm sure I have more than that. I find I get much the same feeling watching the values ever increasing as I would watching some arbitrary number increase. You're watching the grains of sand fall through the hourglass.
