Agreed, Sean. But read that wiki entry I ref to, & contemplate the differences within the parameters established in various adjacent nations; & reflect that there is no consensus as to precisely where within the life-cycle that 'Nurture' to which you appeal should take legal effect. So, I reiterate, a legal concept, not a law of nature -- nor yet, fwiw, an inalienable or unalterable law of nurture!
