I think a near constant awareness of one's own mortality is an inspiring, motivating, (soul-crushing), and ultimately perspective-focusing endeavor that everybody should undertake. That's why I made a wearable to help me!

In short, it's a wrist-worn Adafruit Circuit Playground that displays a randomly generated (but statistically informed) number of days I have left to live. Fun!

Basic premise is: it operates on code that randomly generates these days based on an actuarial table I found that gave me the probability I would die in various age blocks. So every now and then it'll change -- one day it'll say I have 23,454 days left, another only 19. And it's all on a randomized timer as well, so I never know when it'll change, allowing it to catch me off guard and hopefully make me shift perspective in that moment and internalize that life expectancy.

I was inspired by a quote I found in Alan Watt's "The Book",

"The sole means now for the saving of the beings of the planet Earth would be to implant again into their presences a new organ … of such properties that every one of these unfortunates during the process of existence should constantly sense and be cognizant of the inevitability of his own death as well as the death of everyone upon whom his eyes or attention rests. Only such a sensation and such a cognizance can now destroy the egoism completely crystallized in them..." -- G.I. Gurdjieff

and thought it would be cool to make this "organ" into a device I could wear.
