Yeah, I think that's a good question. Everybody is different; some may get different things out of it.
It's obviously going to be wrong in terms of exactness, but likely will be roughly right in terms of framing. That is, if you have 50 years, 3 days, and 2 seconds left, it might actually be 48 or 55 years, but the exact timing doesn't matter so much to me. It's more the quantification of the information that's implicit in our lives but for some reason we don't normally think about unless it's a particularly harrowing experience.
For myself, I spent some time in the ER last year. I honestly didn't know whether I'd live or not. It made me think really hard about what I was doing with what I was given. This serves as a reminder for me to do things that matter. To not optimize for the hour or the day, but the decades.
Plus it was fun to build.
Happy Thanksgiving,
Long
