When history repeats social behavior daily, parallel events happen every generation gap existing in series of generation gaps changing population daily and one at a time combined into the whole numbers here today/this rotation of the planet people count the rotations they have been alive since day of birth.
Omitting 0-9 months since conceived. Oops the never missing, missing link in factuality of being alive so far.
Kind of like a rotation of the planet is completed in 23 hours 56 minutes and 4 seconds a rotation and mankind's facts add 3 minutes and 56 seconds a day mechanically. That sure blows the hell out of quantum physics is just inventing ways to deny how evolving works naturally.
