I would love for this to be extended by a time scale. Same math, but split up into the four quarters of life. My 'hope' would be that a lot of the probability of things going wrong around you shifts towards the later stages?
If something didnt happen, that something happening being a change, there would be no time, as time is a measurement of the smallest increment of change.
Well, in the long run we're all dead, right?
No math involved and you probably don't have to experience it.
