Interesting idea. Do people not find stressful a clock counting down on them constantly? I've always been stressed out by the idea of time "running out" in various contexts (games, tests in school). So much so that it hinders my performance.
Watching Maker Clock count down from 1000 each year of the rest of my life would not be too stressful. I will grant that a clock that counted down from 50,000 or so to zero on my expected deathbed would not be as zen-like as the Maker Clock purports to be. Just calculating that number is zen-like, but a daily reminder would not be.
A warning: if you're stressed out by the idea of time running out, don't click this link. But I found this graphic description of the years, months, and weeks in a typical life to be surprising: http://waitbutwhy.com/2014/05/life-weeks.html I don't typically think of a year or a week as lasting as long as it appears to in those images.
It's a numerical representation of the time left in a year. I like to think of it as 35 chances to make meaningful progress on important things in 2016.
