Oh agreed. My awesome life is not a good proof, but while I came with a high IQ out of the box, I hadn't learned the tools of thinking yet to the necessary degree. It's loosely confirmatory, but not a silver bullet. I was just saying that prompted me to have the idea a decade or two before (inadequitely still, but I knew it) testing the idea. My confidence may be too high, but really, it hasn't been a priority to test mostly because I can't think of a good one that doesn't come at too high a cost for too little benefit. I've never really tried to prove my Fiancé's aunt who I've never met exists either. Open to ideas.

And the grandkids thing is something I came up with to give my fiancé perspective when she was just my girlfriend. Anything with "illion" in it becomes "a bunch" to non math folk. Think about 4 mil. Now think about 8. I'd say (based on nothing but anecdote) if you said each to fifty men-on-the-street, you'd have at least 85 people thinking of pretty much the same pile of gold doubloons.
