メトセラの子ら

Heinlein's portrayal of an extended lifespan challenging social norms is fascinating. I wonder what real-world ideas or fears influenced this vision.

The book explores genetic selection and societal control, which can be uncomfortable. How did others interpret the moral implications Heinlein raises?

Listening to the narration added a different dimension to the characters and pacing. Did it change how you connected with the story compared to reading the print version?
