In this segment, Margherita talks about her choice not to have children and also discusses her position regarding God. She can't prove he exists nor can she prove he doesn't.

Even though Aldo and Margherita were very different in many ways, they came together in their skepticism. Towards the end of her life, Margherita couldn't move around much, but her brain never stopped going.
