@DrGaborMate is correct, it is time to ditch the mythological normalcy we have subscribed to — and perhaps through recognition of this, we can find a greater connectedness as unique human beings no longer challenging our value against an ever-changing target of normalcy.

While this simplified list does not take into consideration pedigree collapse (in which two people share the same ancestor), it is thought-provoking and opens up reflection on the experiences - many horrific - of those before us who endured.
In our daily mundane lives it is entirely too easy to experience an amnesia as to our very limited placement in a nearly-endless universe. Events like these are symbolic reminders that helps us ‘break the mold’ of our limited thinking that this pretty rock is all there is.
