Our ancestors have much to answer for.Why? What did they do?....Long ago, they used machines and drugs to keep the unhealthy and unfit ones of us alive. In that past time it was believed that all persons must have children. It was a right deemed so precious that it was forced upon even those who did not value it or should not have had it. If one of our people became pregnant, our people used all their knowledge to assure the young would be born, no matter how sick or disabled. Then, if the young lived, they injected them and dosed them and radiated them and transfused and transplanted them, to keep them alive, and then, when they were grown, they used all their skills in assisting them to have children of their own.
