Rather than pointing to seven generations counted from one's own and looking toward the future, there is an awareness of a legacy to honor or a debt to bear in mind to those three generations before one's own, as well as an awareness of one's own legacy bequeathed to the three generations to follow one's own.By reckoning 25 years per generation, the span of lifetimes stretches 75 years before one's birth and 75 years beyond one's death.[1]
