In 1953 Crick & Watson discovered DNA.

And in 1953 TPTB changed the International Music Standard from 432Hz to 440Hz & over 20,000 musicians protested not so much about the quality of the sound although that was part of it but more so the fact that making that change would cause great disharmony.

In ancient China their government employed a 432Hz Sheriff who kept a eye on all the musicians enforcing the 432Hz frequency.

Their are many more interesting facts about 432Hz & indeed the year 1953 however I have often wondered if by changing the IMS we changed the future course of history & what would the parallel 432Hz timeline reality look like if we hadn't of changed the frequency & what would have happens if they changed the IMS to something healthier like 528Hz?

Incidentally all the healing Solfeggio's & 432Hz feature on the Tesla 369 vortex mathematics grid? So why do the technology corporations & the IMS tune to the destructive 440Hz.

All this might well tie in with resonance & harmony which may support dating someone of the same blood type.
