Just had one of those long, weird dreams that seemed to go on forever.
In the dream I was a completely different person, and my perspective was sometimes from the outside watching it like a move (though I didn’t notice this fact until I thought about it after waking up).
Sometimes I feel like that in my real life too.
The me in the dream had a tattoo that had his “expiration date,” which had been determined as a lifespan estimate by a blood test.
When I woke up, I thought that would make a good tattoo, and you could use Myan numbers to make it look cool.
Then I though I might write that as a phone app, and have it change the estimate every day (since the older you get, the more likely it gets that you’ll get older to a point). And, I thought you could switch between displays and have an open oval (each representing a day to be filled) or regular numbers the person understands as well as the Myan default.
A way to look at your phone, and at a glance see a graphic of the likely time you had left.
Could also have a white and yellow ac like a plane, since there are certain years that are years that are more likely to be useful for certain endeavors.
Stretch goal idea: Now thinking about it, it should show a birth to death rep graphs too, and could go all out with key events (yours and abroad) that happened in your life. And of course a sexy girl voice AI to encourage ways to accomplish more and tell you jokes that give perspective on your life.
