Common sense comes within shared ancestrally used vocabulary building artificial tomorrows 7 days a week 52 weeks a year regardless the year has 365 or 366 days.
Common since conceived is how populations existed since inception of homo sapiens chronological ancestral lineages occupying time by 5 generation gaps living in series parallel time today no ancestor arrived in two separate generation gaps as last great great grandchild generation arrives 9 months average after conception to become a citizen of reality cradle to grave daily here.
Character doesn't count until everyone is ignoring how evolving works in plain sight, here in this atmosphere. Today that amounts to over 8.096 billion people in 5 generation ancestral lineages having up to 5 gaps so far living and alive eternally separated per heart beat and personal brain navigating the situation by rule of law protecting reasonable doubt now cannot be eternity in any global court system.
