First off no one is exploiting anyone. Employment is voluntary, and mutually beneficial. Secondly, you aren't endangering any healthy young woman's life through pregnancy. You are, however, endangering the old woman's life regardless of how many sit ups she does. That is just nature. No one is talking about forcibly impregnating an unhealthy poor woman. How you managed to twist this all up into such an irrational and absurd narrative is simply insane.
