Negligible senescence.
You know, I posted a crack pot conspiracy theory topic on Movie Codec Lounge about 3 years ago talking about negligible senescence and natural selection of humans as Emperors and Leaders 3000-2000 years ago and what that could say about modern society.
If a man or woman born with negligible senescence lives an extremely long time than they have the potential to father many children with those same traits, and a female with negligible senescence could mother children well into her 70s.
If high intelligence, dominating willpower, good money-management are all desirable traits, than it is likely these long-lived peoples will all eventually bear children with those who have these other traits. What you get are a series of prodigious, long-lived, clandestine families who were likely rulers.
Any good way sto test the hypothesis? Who are incredibly smart people who disappeared and were never heard from again? Are there hospitals specifically for their own? What happens to unusually gifted people that aren't born in these special anonymous hospitals? Where is all the money going?
When in doubt, follow the money. In the 1960s American banks irrationally printed trillions of extra dollars and our government has been illogically shutting down R&D programs, slashing funding. These two developments effectively destroyed an emerging techno-utopian America. Vietnam, the Iraq Invasion, made and still make no sense. Perhaps our Government is at the stranglehold of these anonymous, clandestine bankers who've managed to print trillions of extra dollars and electronically reroute non-existent backings after the Gold Standard was abolished?
Look for money that has no resources to back it. Look for how American bankers may be negotiating with Oil Companies in the Middle East, maybe we'll find the real reason we invaded Iraq. Where did the money come from to build the Burj Dubai. Why is there this massive economic boom in the Middle East? Why are they building taller and better skyscrapers than us?
Are there clandestine families operating in secret? Interacting through Transcontinental Subterranean Vactrain transportation systems?
Tall, blond hair, blue eyes, the Aryans, the Nephilim. They could be behind modern society now, puppet masters.
